How do I create colums within a colum

Hi Looky

You can't.
A column is a column with a column letter or column number identifier and
cannot be split.

You can give the "appearance" of a split column, by having a number of cells
set as Merged, with the cells below not being Merged.

I would STRONGLY advise against ever using Merged cells - it will come back
to bite you at some stage.
Instead, choose Format>Cells>Alignment>Horizontal>Center across selection

This will give the same "appearance", without the other pitfalls of merged
cells.
