I have used codes to create uitable table and the numbers numbers displayed are in 4 decimal places. How can I change it to an integer or a 2 decimal place?

在 MATLAB Online 中打开

data=rand(3,4);
d=arrayfun(@(x) sprintf('%.2f\n',x),data,'un',0)
h=uitable('Data',d,'Units','norm', 'Position',[0,.75,1,.25]);

One thing to note about this is that it makes the entries in the table into strings rather than numeric values. uitable() does not have any mechanism for formatting numeric entries other than is provided for by the ColumnFormat property which allows 'short', 'long', 'bank' and the other items permitted by the format() command. To go beyond those you need to output strings to the uitable. If you later use the uitable to compute with, be sure to convert back from strings to numeric form.
