Allow global search on Table visualization

Hi,

I had a use-case of showing some data via visualization, where the columns of the table would vary based on the inputs, and I wanted a search that would search on all of the columns in the table. Since the column names/number of columns would vary based on the input, I couldn’t just mark all those fields as searchable in the configurations, so I ended up with a fork of the existing Table viz and exposed this as a config, if checked the search would work over all of the columns. If this is something that sounds interesting in the current Table-viz I would love to contribute it back here.

Cheers!
