LO Writer supports paragraph-level widow/orphan control: Not letting a paragraph have just its first k lines or last k lines separate from all the rest (on a different page). I suggest having a similar feature for table rows, w.r.t. lines within them (or rather, lines within the paragraphs within them): Don't allow a row to break across pages or columns when its first or last part has no more than k lines. Paragraphs are inconsequential here, in the sense that it doesn't matter if the k lines belong to k paragraphs or less-than-k or even a single paragraph. Naturally, per-paragraph widow-orphan settings would also apply.
The motivation: Similar to paragraph widow-orphan control, but when you have a table row with many paragraphs, so that intra-paragraph widow-orphan settings don't prevent the table from having just a small part on the first page, e.g. one line of contents and the repeating header lines. That looks kind of iffy.
I would expect, that paragraph-level widow/orphan control also works in in tables, but obviously it doesn't. But this is bug 86909 *** This bug has been marked as a duplicate of bug 86909 ***
