}
if(repeatCount == 0) {

When formatting a table, for instance, you may want the
columns to have similar width without interrupting the width of the table. If you
are using Microsoft word 2000, 2002 or 2003, you should select the table itself;
choose Table option, Autofit, and then select Distribute columns evenly. If
using word 2007 and Later, you should select the table and this will display
the Layout tab. Click the Distribute Columns option tool.
