Well, without code to look at, it's hard to point out what may have done wrong -- a simple test here worked just fine...

p=[20    20   210    80];
hUIF=uifigure('Position',p);
hUIT=uitable(hUIF,'Position',p,'Data',[129640 pi],'ColumnName',{'x','y'},'ColumnWidth',{60 120});
hUIT.ColumnFormat={'short','long'};

Changing the 'ColumnWidth', 'ColumnFormat' properties modifies the table as expected. NOTA BENE: the formatting options aren't very extensive, one of the values recognized by the format function or just one of {'char','logical','numeric'}, ignoring the pop-up menu thingie. Unfortunately, as with the builtin table, setting a specific format string for a given variable/column isn't supported; to do that you'd have to display everything as text and use callback function to format and then display the value.

hi, i try :

>> whos T

Name Size Bytes Class Attributes

T 82x9 40113 table

app.UITable.Data=T;

app.UITable.ColumnWidth={250,80,80,80,80,80,80,80};

app.UITable.ColumnFormat='char','char','char','char','char','short','short','short','short'};

the property columnwidth is setting correctly but the columns format no

Read the doc again; when you use a MATLAB table then "...unlike other types of arrays that Table UI components support, table array data does not display according to the ColumnFormat property of the Table UI component.". It's not in the top level page of the doc, but at <Display Tabular Data in Apps> at the bottom See Also section of uitable

ok but at this point what do you recommend to shorten the number? I also tried with str2num(c) but the result is the same

[Luca Re]

it's weird anyway Line #1 and line #5 have 6 digits but are displayed differently

Are you still trying to use fixed width columns? If so, try either 'auto' of 'fit' for the numeric columns and see if that helps.

It is very difficult to compute the number of pixels to hold aribtrary number of characters given the variable nature of fonts, fontsize, etc., etc., etc., ... numbers with eights (8) or other wider characters in them will need more display space than a number of the same number of digits comprised of "not so wide" characters. Unless, of course, you revert to a fixed-width font.

ok..i solve it removing the decimal numbers decimal
