If you set a table as Inline In Text and add or subtract rows to it, it will not:
respect the following text when rows are added. I.e it will overlap the following text
the table placement shifts up, even beyond the text frame it's inside, when rows are subtracted. At least when the table is at the top of a page - I haven't bothered to check if it happens if the table's vertical position elsewhere on a physical page.
If you toggle the table to Pinned, then back to Floating With Text, then back to Inline, the program catches up.
If you just toggle Inline In Text off, then on, other weirdness ensues. Try it.
This bug aside:
Please Serif, do give some priority to improving tables. The whole implementation (inserting, page breaking, editing, pasting, etc) feels clunky to the point where I don't feel like using Apub for documents relying on tables. MS Word is currently a better solution is these cases, in my opinion.
