I have a table that is breaking to the next page.

Check keep with next/prev for the anchoring para, and the following para.

Check space above/below table to see if it's pretending to be too large.

Set table Row Format to declare that you want it all to stay together.

Cell margins (both in Table def, and cell para def) may need to be adjusted in extreme cases to compact overall table height.

Obscure possibility - table is on Master Page format that is too short.
