Polygrid columns not fully clearing when pgColumns is set

Aha, I was setting pgColumns to the fewer columns and THEN pgData to the 
smaller data set to match the columns

You need to clear the pgData (set to empty) first, then set the columns, 
then set the new pgData.

Perhaps this is a documentation bug?
