Conditional formatting based on other column value

[BOIOpenBanking]

I tried to add a conditional format to a range of cells (column X) that means:
Color all the cells in column X that their value is different than the value on the same row in column Y.
I need to do it in C# , dynamically, without a loop.

What is the expected behavior or new feature?

I expect that will be a way to do something like this:
` int StatusX = worksheet.FirstRowUsed().CellsUsed().First(c => c.Value.ToString() == "StatusX ").Address.ColumnNumber;
var StatusXRange= worksheet.Column(StatusX);

                int StatusY= worksheet.FirstRowUsed().CellsUsed().First(c => c.Value.ToString() == "StatusY").Address.ColumnNumber;
                var StatusYRange = worksheet.Column(StatusY);

                StatusYRange.AddConditionalFormat().WhenIsTrue(StatusY.Value!=StatusX.value).Fill.SetBackgroundColor(XLColor.Cyan); `
               [//How] should I do it?

What is the best way to do it?

the solution is:
" // Convert column indices to letters for A1-style referencing
string statusXColumnLetter = XLHelper.GetColumnLetterFromNumber(StatusXColumn);
string statusYColumnLetter = XLHelper.GetColumnLetterFromNumber(StatusYColumn);

                    var StatusXRange = worksheet.Range(2,StatusXColumn, worksheet.LastRowUsed().RowNumber(),StatusXColumn);

                    string formula = $"AND(${statusXColumnLetter}2<>\"\",${statusYColumnLetter}2<>${statusXColumnLetter}2)";
                    StatusXRange.AddConditionalFormat().WhenIsTrue(formula).Font.FontColor = XLColor.Red;
