Reply To: Calculate in tabels

It’s not doing it in Indesign, but if you link to an Excel table, you can update the linked file and maintain the formatting. Or just copy the column, paste to Excel, do the math, and then copy & paste it back in. Not ideal for a long document but it’s worth mentioning for just a few tables because when you paste into a table from outside of Indesign, you can retain the Indesign formatting.
