Freezing a Column in Table w/ SQL Query as Datasource

[bmorrell-alp]

I have set up a table component using a SQL query as the datasource. With a table built off of a regular data table, the column assigned as the Display Column would automatically be frozen so it appears as the user horizontally scrolls across the table.

However, the query data source does not have a Display Column, and it doesn't appear as though I can set one within the table settings. I have tried to mess with the Custom CSS in the style settings for the table, but have not had any success (though admittedly my CSS knowledge is lacking).

Is there a way I can 'freeze' the first column (or first set of columns) in this table so they remain in view while horizontally scrolling? (for what it's worth, I have also tried using the custom Super Table plugin, but for various other reasons, that component doesn't quite fit my needs for displaying this data)
