rows and column borders

[lastsamuel]

I need a different number cells(columns) across a larger number of columns
with he same left and right outside margins. the spacing is important. 6
columns below with 5 cells in the top row that I can move the left and right
margin of each cell. It must be possible.

Hi
if I understand you correctly that is not possible. You can't split
cells for only some rows. Some things you may try instead:
- for the heading row have a look at 'Format - Cells - Alignment' and
choose 'Center across selection
- maybe merging cells (in the same dialog) works for you. Note: merged
cells cause problems for sorting, filtering, etc.
