In a Google Spreadsheet, I have a column with values like T1, T2, T13 (i.e. all values starting with the same text prefix). I would like to use a formula on the numerical part of the values of these cells (for conditional formatting). Can I somehow apply it only to the numeric part of the value, i.e. 1, 2, 13? I would like to change the background colour for the cell containing the maximum numeric part of the value?
