The only way to do that is to create a new variable and add the values there, or loop through it and write each value to Excel separately.
You could use Create new data table with less columns and then add rows to that table as %[DataRow[0], DataRow[1], DataRow[2]]% or, if you want to do it directly from the table variable, you need to provide a row index, too: %[DataTable[0][0], DataTable[0][1], DataTable[0][2]]%.
I would, however, suggest that you simply modify your extraction, so you only extract relevant data and do not have the irrelevant value at all. This would allow you to avoid having an intermediary table created.
