odp file with a tall table

A table usually can't be shrunk vertically below a certain point (i.e. the rows can't be shrunk below a minimum height). This can be circumvented by selecting the table and changing its point size (say, to 10pt): after this, the table can be shrunk more than it could before.

After this resizing, when the file is saved, closed, and opened again, the table returns to its original point size and to its original overall size (even if the table with the new size is too big and partially goes below the edge of the slide).

The problem might also be with the file _loading_, I can't be sure. The attached file has been saved with a table that fits completely in the slide, and with point size 10 (for the table itself), but goes back to 18pt table that goes partially out of the slide when reloading the file.
