Dynamic Tables

[Logic-gate]

It appears that the current codebase only works for FTXUS; which is not very useful for others. Aside from specific calls, rich.table is the main issue. I suggest moving back to pandas dataframes and then dynamically creating rich.tables from those them. Style will be unified, as in not specific colors for any given column.
