I still have work to do on getting it all to look decent, but I did find out how to create a column filter, based on an answer here.

PivotTable pvt = pc.CreatePivotTable(_xlPivotTableSheet.Range["A8"], "PivotTable");

pvt.PivotFields("Description").Orientation = XlPivotFieldOrientation.xlRowField;
pvt.PivotFields("MonthYr").Orientation = XlPivotFieldOrientation.xlColumnField;
