No, it applies to anything that happens, I think.



@officeboy BTW to group contiguous tabs, select the first and the last while holding the Shift key down.
For non contiguous tabs, hold the Ctrl key down

Thanks! I only adjusted the column widths on the 1st sheet so it now has all specific widths for the columns in use. But it seems too late now, because grouping the worksheets should be done before doing column width adjustment.

Is there way to apply the column width setting to other worksheet afterward, say when you suddenly find your workbook needs to include one more worksheet?
