I don't know of any way.
I can offer an cheat way - and I don't normally cheat - but in this case I would.
Put the word "Continued" in the header row at the start.
Then mask it with a white frame (or whatever colour is behind it.)
Then anchor that frame outside the table, so it will flow with the table.
I don't follow?

I'm sure this is correct but it's not working in my situation. (Bear with me, you're clearly much more of an expert than me.)
I have two header rows to start with. The top one is already a merged cell. So I figure I need to add THREE rows above my header rows, copy the headers into the second two rows, and type "Table 124. (continued)" into the first (already merged and designated as header) row. And then skip the first occurrence of the header in the table setup (which of course shows that I have 5 header rows).
When I do this though, I wind up with no headers EXCEPT at the head of tables continuing from a previous page, exactly as if all I'd done is change the table setup.
I should also mention I'm generating the tables using the plugin "EasyCatalog" - if that matters.
I'd also ideally like to be able to add a footer saying "continued" that appears only at the bottom of tables that continue onto the text page. It's actually kind of amazing that InDesign hasn't thought of making these sorts of things simple options in the table setup.
Here's a screen shot showing a spread so you see what I'm trying to do - I have the "continued"s as I want to add them in magenta. (Blacked out trade names just in case.)
Well, the Footer shouldn't be a big deal; at the end of your table add a row that spans thru all your columns containing "Continued" (if you want, even "Continued on page <next page marker>) and convert this row to Footer Row. Then, in Table Options, go to Headers and Footers tab and select "Skip last" in the Footer section.
That should've been obvious Thanx. Funny, I've been using InDesign for many years, but I've never gotten really in depth with a lot of the features - feel like I'm learning new things every day with this catalog project I'm on.
That's true for me as well. Every time I start a project a little different from the usual at the beginnig I feel uncomfortable, then I realize that it can be an extraordinary opportunity to learn something new.
BTW, let us know if you can manage your header thing; I'm ALWAYS facing the same problems, would be so useful…
