I'm currently working on updating the index of an old catalog, we arent removing anything just adding things, but the way its formatted I need to add rows in the middle of the current tables that are already in the catalog. Every time I try to add a new row, the current last row in the table disappears and can't seem to be found unless I undo the action.
How can I make this last row connect to table on the following pages, and the pages after that instead of continuously losing rows.
Tables always exist in text frames.
If you your table is currently filling its text frame, and you add another row, you will overset the text frame. You'll see a red + sign at the bottom of the frame. You either need to enlarge the text frame, or continue the text flow to another page.
How do I get the text flow to continue to another page?
It just disappears.
Either drag the center bottom handle of the text frame down to enlarge the frame. Or, use the Selection tool to click the red + sign, and continue the text flow on another page.
Here's an InDesign Help article on threading text which may help:
