The size of the data to be added to the table must be compatible with the dimensions of the table, which is what the error message (explicitly) states as well.

Use -

T.ColumnWidth = [50;30;30;30;30;30;30;30;30];

Can you attach the variable T?

I somehow mixed up the dimensions, Sorry.

The table has 73 rows, thus the data for ColumnWidth should have 73 rows as well.

Do you want to add the data related to a variable present in the column? Or is there a criteria/logic for adding that data?

It seems like you are confusing the table data object with the uitable graphics object.

If you have a uitable (UIT) whose data is a table variable (T)

UIT = uitable(); % create a uitable (graphics object)
UIT.Data = T;    % set the uitable's Data to be the table variable T

Then you can set the ColumnWidth of the uitable like this:

UIT.ColumnWidth = {50,30,30,30,30,30,30,30,30}; % UIT has 9 columns

However, using the same syntax on the table variable T tries to add a variable/column called "ColumnWidth" to the table T, which produces an error in this case because the number of values given doesn't match the number of rows of T.

T.ColumnWidth = {50,30,30,30,30,30,30,30,30} % T has 73 rows, so this doesn't work

I want to set the maximum width for the columns (9)

i create table with

"T=table('Size',[nrows,numel(VNAMES)],'VariableTypes',VTYPES,'VariableNames',VNAMES);

At this point I don't understand how I can set the width of the columns
