Is it possible to control the precision of a numeric value displayed in a UITABLE in MATLAB 7.6 (R2008a)?

I am currently using the the list of available formats, given in the FORMAT function in MATLAB, to select the precision of a numeric value in a UITABLE. However, I would like to have more control over the format. For example, I want to control the number of digits displayed before and after the decimal point.

The ability to control the precision of a number in UITABLE, besides using the FORMAT function, is not available in MATLAB.

To work around this issue, one can use the SPRINTF function to control the precision of the numeric value displayed. As an example, consider the following code:

 

f = figure('Position',[100 100 400 150]);
dat =  {6.125, 456.3457, true,  'Fixed';...
        6.75,  510.2342, false, 'Adjustable';...   
        7,     658.2,    false, 'Fixed';};
columnname =   {'Rate', 'Amount', 'Available', 'Fixed/Adj'};
columnformat = {'numeric', 'bank', [], {'Fixed' 'Adjustable'}}; 
columneditable =  [false false true true]; 
t = uitable('Units','normalized','Position',...
            [0.1 0.1 0.9 0.9], 'Data', dat,... 
            'ColumnName', columnname,...
            'ColumnFormat', columnformat,...
            'ColumnEditable', columneditable);

data = get(t, 'data');

for i = 1:numel(data)
    if(isnumeric(data{i}))
        tempStr = sprintf('%2.4g', data{i});
        data{i} = tempStr;       
    end
end

set(t, 'data', data);

This creates a UITABLE and allows the user to control the precision of the numeric value using the SPRINTF function.
