Sean was telling us:
Sean nous racontait que :

Apologies if I wasn't clear, I'm not refering to an individual row
being split across a page, this is where multiple rows may be forced
to the next page following a change in the number of columns in the
table, sometimes leaving the majority of the previous page blank.
I'm trying to set up a simple test case to demonstrate this as I feel
it may have something to do with the style settings, but I believe
the styles are the same across the table.


I still do not understand.
Adding columns will not affect the row distribution, unless you have merged
cells.
In whish case you have to look at space before/after paragraphs, line
spacing, keep with next and/or widow/orphan line settings (paragraph
format); or rows allowed to break or not or automatically adjust cells to
fit content (Table properties).
