AutoCAD tables link to excel sheet problems

I have 2 problems with linking excel table to AutoCAD table

1. I don't know how to export the table style once the AutoCAD table is linked to the excel table so I can reuse it
2. When I linked the excel table to the AutoCAD table, my suscripted text from the excel table don't show up correctly.  It showed up as normal text in the AutoCAD table.

Below is an image of my problem #2

Any help would be appreciated.

Thanks!
