There are 2 questions on the tables

Hello. There are 2 questions on the tables. 1. How can I change the background of a cell depending on the value of the cell itself? 2. How can I sum a column or use formulas by type like in Excel?

Hi,

Is this question related to tables in XWiki? What editor are you using to create your tables? Have you tried something so far?
This can be achieved by writing code (velocity or JS).

Hope it helps,
Alex
