Hi, i have a table in a subplot having also three histograms. I want to display in the table only two decimals and i don't know how to do it. This is my code:

clear; close all;
load('data')
.....
h = subplot(2,2,4);                  
hPos = get(h, 'Position');           
tt = {'average';'standard dev.'; '% no rebound'};
MAC = [mean_MAC; std_MAC; mean_perc_zero_MAC];   % here
OMT= [mean_OMT; std_OMT; mean_perc_zero_OMT];
ACC = [mean_ACC; std_ACC; mean_perc_zero_ACC];
T = table(MAC,OMT,ACC,'RowNames',tt);
uitable('Data',T{:,:},'ColumnName',T.Properties.VariableNames,...
  'RowName',T.Properties.RowNames,'Units', 'Normalized', 'Position', hPos);  
set(h, 'Visible', 'Off')

Don't have that much flexibility with numeric formattting in the object, sorry.

uitable uses the same setting as the command window for its 'numeric' keyword. You could set the 'ColumnFormat' to the string 'Bank' that does use two decimal places as the easiest workaround.

Seems like reasonable enhancement request; I have no idea how complicated it would be to implement a general formatting facility to set '%.2f', for example, as to whether there would be any chance at all of such being ever implemented.

The alternative is to write a CellEditCallback function and format the data as desired but then display it as character string, not numeric.
