Adding a merged column row above a Datatable table header

DataTable output:
P1

Intended output:

How would one go about doing so?

Hi @theachilles96 ,

You can use the Invoke VBA Activity, with the following Code,
sub AddMergedHeader()

Rows("1:1").Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove

Range("A1:D1").Merge
Range("A1").Value = "Particulars"
Range("A1").HorizontalAlignment = xlCenter

end Sub

Hope this helps!
