How can I make a row of a tablix occupy the remaining space of a page?
Things I tried:
- Create a new empty row and adjust its height to occupy the page, but this row has a fixed height meaning if I have more data the table will expand to the next page
- I changed
CanShrink
and CanGrow
without avail
- Changed the cell height instead of row height it gives the same behavior as before
I'm afraid it won't be possible to do this.
Only if the report takes only one page
One way to do this is to separate the totals into a different table and use rectangles to simulate the columns.

Found a workaround that works for multiple pages (almost)
- Place the 1st table contents inside a rectangle
- Enable Add a page break after, in the rectangle properties
- Place the totals outside the rectangle
- keep using rectangles to simulate do columns (those rectangles need to be inside the rectangle that breaks the page
- Done
