Uitable Decimal Places How To?

currently some of my Uitable is decimal and some is scientific notation. I would like to make it all decimal and be able to control the number of decimal places. Anyone know how to set the output to decimal and be able to change the number of decimals in the context of my code? (below)

f = figure('Position',[1 1 500 250]);

%Row and column names
cnames = {'C1','C2'};
rnames = {'R1','R2','R3'...
    'R4', 'R5', 'R6'...
    'R7','R8',...
    'R9', 'R10'...
    'R11' };

% create the data
d = [SmI SmD ; RmI RmD ; KmI KmD ; RthI RthD;QjthI QjthD;...
    QjthISS QjthDSS;QpcI QpcD; QpcISS QpcDSS; QphI QphD;...
    QphISS QphDSS;ZmI ZmD];

% Create the uitable
t = uitable('Data',d,...
            'ColumnName',cnames,... 
            'RowName',rnames);

% Set width and height
tableextent = get(t,'Extent');
oldposition = get(t,'Position');
newposition = [oldposition(1) oldposition(2) tableextent(3)...
    tableextent(4)];
set(t, 'Position', newposition);

Nobdy? I got the same problem. It might just be writing '%.2f' somewhere. But i cant figure out where.

There is no control of the individual numeric entries other than...

https://www.mathworks.com/help/matlab/ref/matlab.ui.control.table.html#bvboy7l-1-ColumnFormat

ColumnFormat: "A string accepted by the format function, such as: 'short', 'bank', 'long'"

For anything more complex than that you need to convert the numeric entries to strings and display the strings.

I cannot find any documentation regarding these column format options - are they now obsolete?

So in 6 years, Matlab still haven't added the ability to control decimation in a uitable?

Thanks for the URL update,, @Pierre Harouimi

Building on Walter's answer, I found reformatting data in a cell string useful.

Try a variation of this (left pad each string to 9 characters):

d = cellstr( pad( string( d ), 9, 'left' ) );
uitable( gcf, 'Data', d, 'ColumnFormat',{'char', 'char'} );

This solution will break down at some point for picky users, but it improved my aesthetics in the short term.

[Walter Roberson]

You might also want to switch the font to fixed width.

Another way of getting the padded cells is

d = sprintfc('%9.2f', NumericArray);

[Lee]

why do neither of these methods work when using a table in app designer?

If i create a new figure with table: uitable(gcf, 'Data', d) i see the numbers being pushed to the right. However, if I add a table to my GUI: uitable(app.tab, 'Data', d) the numbers remain left aligned

So even after doing all the adjustments I need with sprintf, the table in my app doesn't look as I want!

[Walter Roberson]

uitable() for uifigure() have a different implementation and slightly different properties than uitable() for traditional figure()

for uifigure() there is the StyleConfigurations property https://www.mathworks.com/help/matlab/ref/matlab.ui.control.table-properties.html?searchHighlight=uitable%20properties&s_tid=srchtitle_uitable%20properties_4#mw_7016c015-778b-48aa-bb90-a726d7f1010d and perhaps uistyle() would allow you to do the appropriate adjustment.

[Lee]

ok thanks, I will give a try. What a complete mess though...

[Nieves]

Just something further on this. I was able to convert to strings, and that looked perfect. However, the sort order was then broken.
