Mathematical Table Filtering

[TravisCouture]

Describe the solution you'd like

The ability to filter a table based on mathematical expressions on columns. E.g. (C1 > n)

Describe alternatives you've considered

Can be done using a form and manipulating the underlying dataframe based on the form input but this feels clunky. I think this should be a native feature of Wave tables.
