Vlad,
I'm glad to see that you're almost done working on tables. Since you're now accepting issue-reports for tables, I thought I'd go ahead and report a couple of issues I've encountered since tables were first introduced. I downloaded build 396 and confirmed that they also exist there.
1. Unable to select a row within a single-column table when the row does not contain text. Since the row can't be selected, it also can't be deleted. (I use single-column tables for my task lists.)
2. Copying a row (or multiple rows) and then pasting to another location either in the same table or in a different table sometimes works, but usually produces unpredictable results. For example, text from an entire row may paste into a single cell, or the text may paste properly across all columns but then a narrow row of lines may be inserted below or above the pasted row (this actually looks as if two tables exist, one right on top of another).
I hope this helps!
