Thanks. That's not working in my document so i tried on a new document and it does work.
This is an ancient project so there may be some file damage. I might need to rebuild from scratch.
I'll try to round trip through idml first.
Interesting new development: The keep options as described above works only if the cells themselves don't have any keep options. If I set the first cell to stay with next cell in the first table, then the table doesn't stay with the second table, the first table remains on the first page.
If the cells don't have to stay together, then the second cell in the first table does get pulled to the second page.
Of course what I need is for both cells to move together to the page with the second table.
Can you nest the two tables into a new two-row, 1 column table?
The first time I tried the settings I show in my post above, they worked perfectly.
I tried it again (same settings) to see what might be happening with yours, and it wouldn't reflow, it just hightlighted the text that should have reflowed:
I don't understand why it's now highlighting instead of reflowing.
