I'm having hard time with tables and column widths.
Update: I'm using XHTML Strict 1.0.
The page is: http://www.pro-turk.net/try
The first problem I have is, I have a column with a fixed width of 100px and 4px padding, but it disobeys my padding depending on the value. The column width (as the distance between two borders according to W3C Box Model) is 156 px even if padding is 0 or 4. Only the position of the text changes.
According to W3C Box Model ( available at www.pro-turk.net/box_model.png ), borders and paddings aren't included in WIDTH attribute, so why does it render wrongly ?
The second problem is, when you look the page I gave with IE8, the first cell in the second row has 150px fixed width, but ie shows it about 50% of the total table width regardless of what i say.
You're using the default auto table-layout mode. That lets the browser decide fairly arbitrarily how much space to assign to each column, usually depending on the amount of actual content in the cells. In this mode, width is little more than advisory.
If you want the browser to take your column widths seriously you should set table-layout: fixed on the <table> element, and either include <col/> elements with explicit widths, or set widths on the cells in the first row, for the columns you want to be fixed-width. (The other columns will share the remain width equally.) fixed table layout also allows the browser to render faster.
For your page you might be better off with CSS positioning. Certainly for the internal table that seems to exist only to float-left the image. Nested tables are to be avoided.

I'm creating a pivot table using jqgrid with group headers. I do some calculation on input data to figure out if combined column width would exceed the fixed width of grid. If it does not exceed then i would change shrinkToFit : truefor grid to occupy full width. If I do it, then dragging column width creates alignment issues between header and body.
Problem gets worse if frozen column are enabled. The fixed header div wont expand like the column underneath it if shrinkToFit is enabled.
Here is a demo to understand the problem : http://codepen.io/anon/pen/NbxWrQ
Any leads will be helpful.
Thanks in advance.
You can use a GeneXus HTML table to layout text blocks and attributes. If I add a second table to contain some other information that I want to conditionally display, quite often, the first cell is a different width to the first cells of the table stacked above it.
How do you make all the columns/cells the same width so that stacked tables display with their contents correctly aligned?
This is for GeneXus Web in Evo 2 & 3.
Thanks
Put a value in the width property of the client table first cell.
So, put the same value in the width property of the password table first cell.
Remember that the width value must be enough for both tables. In your case, the biggest textblock is the "Client Name". So, choose a width enough for that.
Best regards.
If you don't set a width, HTML will assume the minimum width required to accommodate the content. If you don't want it to be set automatically when when the page is displayed, you have to decide on a width.
In your case, you have to put the same width value for a cell (any cell) in the first column of both tables.
i have a function where i manually set the width of a jqgrid column. If I after this want to use the resize handle, it adds or substracts relative from the original width size. So it doesn't see my new width to take as a base. I have tried putting the width and withOrg in the colModel without success.
I have a click handler inwhich i resize a column to a certain width on click. i set the width of the th trought JS. After this i would like to be able to use the .ui-jqgrid-resize element for resizing the column.
a short version of my code, say the th is 200px wide:
$('th').dblclick(function(){
$(this).width('100px');
});
after the user doubleclicked, and the th went smaller in size to 100px, the user uses the resize handle to widen the th 10px. The expected result is a th of 110px wide, but the thjumps to 210px wide. It adds the 10px the user wanted to add to the original state, not the state i have set with the doubleclick.
I would recommend you to use setColWidth method, from the plugin which I wrote before (see the answer), to change the width of the grid column. You can download the current version of the plugin from github.
If you trying to set the width of columns based on the width of the content of the column then I would recommend you to take a look at the demo created for the answer and read the answer too. I don't see the suggested code as final solution, but the demos shows my view on the problem and the ways to implement "autowidth" functionality.
jqGrid edit and view forms row labels (they are same as column captions ) are set at runtime.
Sometimes they are narrow and sometimes wide.
For narrow labels column width in too big. There is too much empty place between label text and value field.
It looks like labelswidth: '30%' value is hard coded.
How to adjust edit and view form labels columns width automatically so that if all labels are narrow, column width is smaller ?
The first which I would try to do is to use the values in pixel instead of percents:
labelswidth: 80, width: 600
I want slickgrid to autosize the columns based on the widest content or header text - whichever is wider. In simpler terms, I want it to simulate the default behavior of regular HTML tables when it comes to column sizing. How can I do it in slickgrid?
When constructing your options, you can use forceFitColumns: true
var options = {
enableCellNavigation: true,
forceFitColumns: true
};
This will make the columns fill the entire width of your grid div.
The OP is looking for columns to grow to match their content. grid.autosizeColumns() grows the cells to fit the parent container, which is not the same thing.
I have added this feature, and it is about as manual as you might imagine. You loop through the displayed cells and measure each one, saving the widest cell and using that width to set the width of your column. SlickGrid gives you good access to the cells in the viewport, so that works nicely.
The measurement algorithm is your big decision. You may put the content off screen and measure it, as #jay suggests. This works, but it is the slowest method, as it requires a repaint to insert, and a repaint when you remove. There may be ways to optimize. The solution I went with is to measure the width of every letter in the alphabet, as well as other typographic characters we come across, and sum them to generate a width. Yes, this sounds absurd. It has many constraints: The font size must be the same, it doesn't support images, there can't be any line returns, and more. If you can live with the constraints though, you can calculate sizes for a huge grid viewport in <5ms, because the character widths are only measured once.
After you get the sizes of the columns, you assign them to your columns using grid.setColumns().
Slickgrid will not support column auto size based on data.You need to write a plugin or fork the slickgrid core to modify.
Here is the link I have created a plugin to handle slickgrid auto size

I added this after the grid is drawn and it works fine.
$(window).resize(function() {
var cols = grid.getColumns();
grid.setColumns(cols);
})
You should be able to call the autosizeColumns() method of the grid object.
grid.autosizeColumns();
Make this simple adjustment to Naresh's https://github.com/naresh-n/slickgrid-column-data-autosize, on the init function:
Add $container.ready(resizeAllColumns); to the init function.
This ensures the columns autoresize on initial load
Insert the text into an off-screen element and retrieve the width of the element. This is what excanvas does to measure text. Use this to set the width of the column since it's expecting a pixel value.
