How to remove entire rows depending if certain columns have NULL or not - Power BI Query

I have an unpivoted table in the Power BI Query with +20 columns and +10000 rows.
The first columns are related to KPI name, month, and other data of interest. The columns after are the columns that contain the actual values I want to display.
Some rows have the KPI description (name, month, etc.) but do NOT any values in the rest of the columns ("NULL").
Is there a way to remove these rows? Remove whenever all the values of the rest of the columns are "NULL". (First columns will never be empty)
Thank you!!
I'm still a beginner in this Power BI world :)
If the other columns are always nulls together, then just pick one of those columns and use the arrow atop the column to remove the tick mark from [ ] null and filter it out
= Table.SelectRows(#"PriorStepName", each (Total number of shipments inbound] <> null)
If you have to check that every column except certain columns have nulls, then you could do this, which counts the number of nulls on each row. Then filter that column for proper number of nulls using the drop down atop that new column
= Table.AddColumn(#"PriorStepName", "Count", each List.NonNullCount(Record.ToList(_)))
Similarly you could count the number of null columns excluding the first X columns (here the first 2 columns) then filter that column
= Table.AddColumn(#"PriorStepName", "Count", each List.NonNullCount(List.Skip(Record.ToList(_),2)))

Oracle update a table where the phones are horizontal from another table where the phones are vertical

In ORACLE I am trying to update a table where the phones are horizontal from the data in another table where the phones are vertical.
I have tried MERGE and UNPIVOT, but these are not working due to the table I am trying to update has many phones, but the data I need to update it with only has one phonenum.
Some accounts have 3 phonenums, some only have 1 phonenum (Vertical-get data from this table)
TableA
phone_num
Account_num
Phone_type
1234567890, 123, CELL
8165558877, 123, CELL
9135889685, 123, LAND
8885551212, 444, CELL
9995551212, 888, CELL
TableB (Horizontal - Update data in this table)
account_num
phone1_num
phone2_num
phone3_num
phone1_type
phone2_type
phone3_type
123,1234567890,8165558877,9135889685, UNKNOWN, UNKNOWN, CELL
444,8885551212,,,UNKNOWN,,
888,9995551212,,,UNKNOWN,,
Final Result should be
123,1234567890,8165558877,9135889685, CELL, CELL, LAND
444,8885551212,,,CELL,,
888,9995551212,,,CELL,,

Kendo UI Grid jQuery top cell value populates other cells within this column

I would like to update all rows inside one column. Each column would have its own input which will update the rest of the rows. Currently I have an existing edit batch table. I was wondeing if it was possible to:
select a column (maybe with checkbox)
Row 1 is empty, however will trigger a function
This function takes the input value (which the user will type) of row 1 cell and populate this value for every row inside the that column.
COL 1 || COL 2
row 1 || row 1
row Z || row Z
After this the user should still be able to activate the cancel button and the original data appears back in the table. The table data should not be saved unless the saved button is pressed.
I've tried a fucntion using a button where we would execute row.set(column, value), however this would refresh the grid table and the original data would reappear.

Displaying multiple values in NSTextField using bindings

I am having an NSTableView with a bound NSArrayController. When one or more rows are selected, I want to show the name of the selected rows in an NSTextField. If only one row is selected the value should be shown, if multiple rows are selected the content "multiple" should be shown in the text field.
I set up my NSTextField bindings as follows:
If the selection of the table view updates, e.g. I select one row the content of the text view gets the following:
(
val1
)
If I select multiple rows the text field shows this content:
(
val2,
val1
)
Why is the text field not properly displaying the contents of the Array?
By accident I found the solution. The binding has to be changed to:
self.arrayController.selection.name
