How to remove formatting from Google Table Visualization

I want to add a bar formatter on the sorted column of Google table viz. So when sorting changes from one column to another I need to remove formatting from my previous sorted column and put it on the new column. And since开发者_运维技巧 formatting is associated with data table, Is there any way to remove formating from the table without redrawing it? May be I am looking for a class like "BarDeformat".
