Justify tables vertically in a page

Hello everyone.
I have many tables with many rows that flow across several pages. The rows are defined with specific measurements in the "top cell inset" and "bottom cell inset."
To make these tables justified/take up the entire page, I've been selecting all the table rows on the page and playing with the "top cell inset" and "bottom cell inset" spacing, trying and changing the spacing until I get it right.
I need a script that does the following:
Find the remaining space to fill the page and distribute that space evenly across all the selected rows.

Does anyone know a script that does this?

I'm uploading a table in InDesign with the .idml extension.

Thank you very much.
