Filter nested tables

[tesh]

I have nested p-tables with row expansion (ie. p-table which has expandable rows and when each row is expanded, it contains a table with no expansion).
I am trying to create a search box that finds all rows of the main table and all rows of the inter tables that contain a match.

Is this possible?

I can do it if I have two search boxes, one for the main table and the other for the inter tables, but am unable to get it to work with one search box that filters both.
