When doing complex table editing I sometimes find it useful to split the table just above & below where I'm making the edits. Otherwise, cell splitting, moving cell borders and the like can have unwanted effects on other rows. Once the row(s) in question have been edited, re-joining the table is as simple as deleting the paragraph breaks inserted by the split process.
