xcelmg.prg is a good example! However, the bExtand code block assumes gluing columns starting from the first one. How do I glue, for example, only 2 and 3 columns ? Is it possible not to show column separators in one line ?
For any column, number of columns returned by bExtend, to the right of the current column are merged with the current column
If aCols[ 3 ]:bMerge returns 3, then columns 3,4,5,6 are merged. ( col 3 to col 3+3 ) If aCols[ 2 ]:bMerge returns 1. columns 2 and 3 are merged ( col 2 to col 2+1 )
