How do i split table colums over multiple pages using xsl fo

I guess you mean something like: you have a 5 column
table and you want to put columns 1-3 on one page and
columns 4 and 5 on the next.
You can't do this directly in XSLFO. XSLFO is not
designed to cater for this kind of layout.

The best approach is to use a page master which
represents two of your pages side-by-side and put the
table so that it looks as if it were split, possibly
adding a column without content and borders to simulate
margins of the pseudo page in the middle. Of course this
will screw automatic page numbering, and it may be
difficult to emulate the static content you want to have
in general. Also, you can't mix this with flowing content.
