I understand that table and cells are supported only in PDFClown version 2.0 but that is only a few months away. So, being stuck with version 1.2, how do I create a spreadsheet having 2 columns (& another spreadsheet having 3 columns)?
Anything with examples to point me in the right direction.
As you noticed, the layout engine supporting tables and lots of other high-level typographic elements is scheduled for 0.2.0 (its Java implementation will be pre-released for evaluation and beta-testing); in the meantime you can coarsely arrange a table this way:
define the table partition (columns) on the page and draw the corresponding rectangles through the PrimitiveComposer;
insert in each column area your contents through BlockComposer, keeping track of the maximum y occupied by your contents (this is calculated when you call BlockComposer.End(), after which you can retrieve the bounding box of your contents via BlockComposer.BoundBox);
when you complete the columns for the current table row, use the maximum y saved in step 2 to draw the bottom line which closes the row and iterate back to step 2 until you run out of rows;
if you run out of space while inserting contents, keep track of the positions returned by BlockComposer.ShowText() and BlockComposer.ShowXObject(): this way you can fill each column, then move to the next page and resume the insertion according to the tracked positions.
This should suffice to get the job done. ;-)

Is there a technique by which I can freeze (say) the leftmost two
columns in a wide Gridbox when scrolling across it? I know that I can do it
using a MatrixEx control, but I need the cells in my grid to hold more than
just alphanumeric data but also lists, toggles and possibly other controls.
One avenue I will explore is having two gridboxes side to side, the
rightmost one in a scrollable container, but what other possibilities exist?
Same Gridbox... I need the ability to reorder rows at the users
request (a move-up/move-down facility to move one row at a time). Emptying
and repopulating the gridbox is one option - what better ones exist?

I have a incredibly large spreadsheet that lists details for the computers in my company's inventory. We need to know how many systems we have that are x years old. I was able to sort it by model but because the model names are wildly different it didn't help much. For example, one model name is
13-inch MacBook Pro (2011)
And another is
13-inch Retina MacBook Pro (Mid 2017)
The only constant value in the parentheses is the year at the end. I'm trying to write a formula that will spit out how many of each system there are. We need to know how many are 2011 computers, how many are 2017, etc. We are fine with grouping up "Early, Mid, Late" since we just need a year separation but those terms don't show up in every cell throwing my math off. The rows don't have to be sorted, I just need a count.
My plan of attack would be to first, convert the spreadsheet into a table using Insert > Table... this enables Excel to manage calculating columns for you.
The following assumes that the cell at the top of your list contains the word "Detail".
Second, I would make a new column at the far right with an equation like this:
=mid([#Detail], find(")",[#Detail])-4, 4)
...and I would tune the "Find" function and the "mid" function until it gives me just the year.
Third, sort the entire table by this new column. Tada!
Transfer the data to column A. Cells A1 to A1000 in my Example.
In Enter the years in column C. Cells C2 to C20 in my example.
In cell D2, enter the following Array Formula, and drag it down.
=SUM(IFERROR(IF(VALUE(LEFT(RIGHT($A$1:$A$1000,5),4))=C2,1,0),"-"))
Array Formulas are entered using Control + Shift + Enter, instead of Enter.
The Formula takes the last 5 characters of all entries in the column A. Then it takes the first 4 characters of this new text (to eliminate the closing bracket) and converts the text entries to numerical values. It matches each entry with the year in column C, and totals the matches.
I hope this solves your problem.

I have a single dataset containing 4 columns, each showing the number of rejections for a quarter-year. A 5th column shows the Team to which those values belong.
Is it possible to add 4 fixed points on the x-Axis, each belonging to one of these columns? Then I could add the Team as the Y-Series. I'd like to see the evolution of each team in time.
Take a look at this example:
http://www.birt-exchange.org/org/devshare/designing-birt-reports/1553-use-column-names-as-chart-xaxis/
I solved this by writing a (really short, really simple) loop which takes the values out of the four mentioned columns, one at a time, and creates four rows instead.
So the rows basically contain the Team from the original row (duplicated 4 times) and the Number of Rejections. So now instead of a Row with one team and four numbers, I have four rows, each with one team and one number.
I did this all in the report scripts (under "fetch"). Try it, it's really easy.
Our team is working on implementation of the table widget for mobile platform (one of the application is mobile office like MS Excel).
We need to optimize the data structure for storing table data (the simple 2-d array is used).
Could you, please, suggest the optimal data structure for storing table data. Below are some of requirements for the data structure:
the size of the table can be up to 2^32 x 2^32;
majority of table cells are empty (i.e. the table is sparse), so is is desirable not to store data for empty cells;
interface of the data structure should support inserting/removing rows and columns;
data structure should allow to iterate through non-empty cells in forward and backward direction;
cells of the table can be merged (i.e. one cell can span more than one row and/or column).
After thinking more about the problem with the row/column insertion/deletion, I've come up with something that looks promising.
First, create and maintain 2 sorted data structures (e.g. search trees) containing all horizontal and all vertical indices that have at least one non-empty cell.
For this table:
ABCDE
1
2*
3 % #
4
5 $
You'd have:
A,B,D,E - used horizontal indices
2,3,5 - used vertical indices
Store those A,B,D,E,2,3,5 index values inside some kind of a node in the 2 aforementioned structures such that you can link something to it knowing the node's address in memory (again, a tree node fits perfectly).
In each cell (non-empty) have a pair of links to the index nodes describing its location (I'm using & to denote a link/reference to a node):
*: &2,&A
%: &3,&B
#: &3,&E
$: &5,&D
This is sufficient to define a table.
Now, how do we handle row/column insertion? We insert the new row/column index into the respective (horizontal or vertical) index data structure and update the index values after it (=to the right or below). Then we add new cells for this new row/column (if any) and link them to the appropriate index nodes.
For example, let's insert a row between rows 3 and 4 and add a cell with # in it at 4C (in the new row):
ABCDE
1
2*
3 % #
4 # <- new row 4
5 <- used to be row 4
6 $ <- used to be row 5
Your index structures are now:
A,B,C(new),D,E - used horizontal indices
2,3,4(new),6(used to be 5) - used vertical indices
The cells now link to the index nodes like this:
*: &2,&A - same as before
%: &3,&B - same as before
#: &3,&E - same as before
#: &4,&C - new cell linking to new index nodes 4 and C
$: &6,&D - used to be &5,&D
But look at the $ cell. It still points to the same two physical nodes as before, it's just that the vertical/row node now contains index 6 instead of index 5.
If there were 100 cells nodes below the $ cell, say occupying only 5 non-empty rows, you'd need to update only 5 indices in the row/vertical index data structure, not 100.
You can delete rows and columns in a similar fashion.
Now, to make this all useful, you also need to be able to locate every cell by its coordinates.
For that you can create another sorted data structure (again, possibly a search tree), where every key is a combination of the addresses of the index nodes and the value is the location of cell data (or the cell data itself).
With that, if you want to get to cell 3B, you find the nodes for 3 and B in the index data structures, take their addresses &3 and &B, combine them into &3*232+&B and use that as a key to locate the % cell in the 3rd data structure I've just defined. (Note: 232 is actually 2pointer size in bits and can vary from system to system.)
Whatever happens to other cells, the addresses &3 and &B in the %'s cell links will remain the same, even if the indices of the % cell change from 3B to something else.
You may develop iteration on top of this easily.
Merging should be feasible too, but I haven't focused on it.
I would suggest just storing Key Value pairs like you would in excel. For example think of your excel document has columns A - AA etc... and rows 1 - 256000...etc So just store the values that have date like in some type of key-value pairs.
For example:
someKeyValueStore = new KeyValueStore();
someData = new Cell(A1,"SomeValue");
someOtherData = new Cell(C2,"SomeOtherValue");
someKeyValueStore.AddKeyValuePair(someData);
someKeyValueStore.AddKeyValuePair(someOtherData);
In this case you don't have to care about empty cells at all. You just have access to the ones that are not empty. Of course you probably would want to keep track of the keys in a collection so you could easily see if you had a value for a particular key or not. But that is essentially the simplest way to handle it.
I'm going to describe my goal in steps because I think that might be the easiest way to explain it. This is what I'm trying to do:
1) Create a template that has various calculations on it. On this template, 1 specific cell is left blank. The calculations will change depending on what's in this cell (I'll refer to this as the special cell).
2) There's one final figure behind these calculations that's important. What I want to do is create a list with every possible final figure and in an adjacent cell, list the value of the special cell that gives this final figure.
The problem is Excel for Mac 2008 doesn't use macros or VBA. In my Windows version of Excel, this is just a simple function. But on Excel for Mac 2008, I'm not sure at all how to tackle this. The only solution I can think of is to create one sheet for every possible value of the special cell, with all the calculations done specifically for that value of the special cell. Then I could just link each final figure/special cell to a main page so all the information is together. However, there are roughly 400 values the special cell can take, and I really don't want to create 400 different sheets. Does anybody know how I can do this?
Also, just as a note in case this is easier to visualize what I mean, I'm basically trying to run multiple what-if scenarios and collect one specific number from each of these scenarios.
Here's an example of the processes involved. I should mention here that there are actual 2 different special cells, I wrote 1 in the original description because I'm assuming the idea would be the same to do 2:
1) The main template sheet is located on Sheet A
2) There are 10 slots for store names
3) Each store has a rate, the rate is found by applying a vlookup which looks up the special cell 1 and where the array table is located on Sheet B
4) Each store also has an index number (referred to as index)
5) Each store has a calculation which is index * special cell 2 (referred to as calc1)
6) Each store has another calculation which is rate * num1 (referred to as calc2)
7) Each store has another index number (referred to as index2)
8) Some of the index2 values have to be multiplied by calc2, the rest will stay the same (referred to as calc3)
9) A summation has to be done, summing all the calc2 values to result in sum1
10) A summation has to be done, summing all the calc3 values to result in sum2
11) The final figure is sum1 + sum2
It sounds like you could create 400 rows where each row is a what if scenario. Then next to each row you could take an input and an output, and graph accordingly.
Update
Per your description so far I've created the attached workbook with some formulas to put you in the right direction:
https://dl.dropbox.com/u/19599049/120813_2c.xlsx
It calculates the sum1 and sum2 For 10 stores based on the 2 inputs.
Note that I colored which cells were ending up in which final output.
yellow = original sum1/sum2
blue = array formula version of sum1/sum2
green = data used in both.
I did this to point out that while this example workbook seems to follow all 11 of your rules. the input 2 doesnt appear to be included in the final outputs of my mock-up version for some reason.
Either way this should serve as a good basis to get you started. And I can modify it if you continue to include more details.
