Hello,

I'm trying to format all numeric table cells based on multiple conditions.

My purpose is to change:

  • Any cell background color to red if cell value >3 or <-3
  • Any cell background color to green if cell value <1 and >-1
  • Rest of cells background color should be yellow.

Please run snippet to get full details.
