fo:table adaptive width after page-break

Question

I use different page layouts for different pages (first/rest) and would like the table to use all available space after a page break. Is there a way to control this in xsl:fo?

Since I use table-headers and optional table-footers to have headers/footers printed on all pages, I can't split the table manually, or at least not to my knowledge, otherwise I would have output each row in a separate fo:table as a workaround, to let the renderer know that the parent container has a different size after the page break.

For the FO -> PDF conversion I use FOP v2.10
