Variable number of inputs in inputdlg with pre-selected values when inputs equals 6

Sometimes I want to replace the column headings in a uitable. I have several uitables and each can have a variable number of columns so I have the following code which uses an inputdlg but with a variable number of inputs.

    T=app.UITable;  
    data=T.Data;          
    [rows,cols]=size(data)
    ReportMessage(app,['UITABLE cols: ',num2str(cols)]);
    dlgtitle = 'Modify Columns Headings....';
    prompts=compose('Col %d',1:cols);
    y=inputdlg(prompts,dlgtitle);
    T.ColumnName=y;
 
    

When the number of columns is 6, I want to pre-select the input entries. Normally I would use this

    definput = {'100','1','31.72','0','123','78'};

But this doesn't work

    if cols==6            
        prompts=compose('Col %d',1:cols);
        definput = {'100','1','31.72','0','123','78'};        
        y=inputdlg(prompts,dlgtitle,definput);        
    end
    T.ColumnName=y;

But this doesn't work

In the inputdlg() call, the third position is field size, not default input.

answer = inputdlg(prompt,dlgtitle,fieldsize,definput)

Perfect, thanks Walter!
