99025_tableColumnBreakAfter.odt: simple, but different outcome, test document.

I'm not sure if this document mimics OP's problem closely enough(it doesn't seem to since it doesn't introduce a continuous sectionbreak), but it does show that the column break on the table is simply not even seen on export of doc, and DOCX also doesn't work properly.

In OP's example, the tables themselves are set with Column-BreakAfter - which Word can't handle directly, so it has to be moved to the following paragraph as a column-BreakBefore. But for some reason it is exporting as continuous section break instead of a manual break (at least, according to Word 2003) - also for DOCX.

P.S. Always using BreakBefore exports nicely.

This one would be really complicated to solve. Somehow, you have to keep track of the fact that the table-start indicates a column-break-after. Then many (cell) paragraphs can go by, and even table-in-table-ends. Then, on the following paragraph (or table), a column-break-before would have to be issued.

At the moment, the column break is never even seem during the DOC export, and it is ignored in DOCX since it isn't a bBefore in an m_bBreakBefore zone.

Since DOC and DOCX share the same export code but work very differently, I'm not even going to attempt to handle this situation. This is a regression disaster waiting to happen.
