Apache FOP | Multi page table row height issue - row

Question

I am generating PDF using Apache FOP XSL file format.
My requirements are
Tabular data in PDF
Table size is large so the Same table extended to multiple pages (width-wise, few columns in first page others are on the next page)
Page 1 has 3 columns (C1, C2, C3)
Page 2 has 5 columns (C4, C5, C6, C7, C8)
Few cells may have multiline data
Problem description:
When Page-2 has multiline data for Row 4, Column 4, so its row height increased as per content
But in Page-1 row 4 has row height as a single line.
I want to have the same row height across all pages of the same table when any cell data is multiline of any page.
Here is XSL file if needed:

What I don't want
Fixed row height as it wastes page space even if all data is accumulated in a single line.

Answer 1

Format the full table twice: once for each page.
For the first copy of the table, make everything after column 3 be white or transparent.
For the second copy of the table, make everything in columns 1 to 3 be white or transparent and also add a negative margin on the table (and set it back to 0 in the table cells) so that columns 1 to 3 are off the left side of the page.
Note that if you were using AH Formatter, you could use the Spread Page Master extension (see https://www.antenna.co.jp/AHF/help/v70e/ahf-spread.html) and make a region that spans both pages.
