Pivot2.0 JavaScript Column Width

My PivotTable has 3 columns. I want javascript to set the width of Column2 to 10px. I've already changed the contents of Column2 to all empty strings.

I tried DOM-manipulation. The Pivot DOM structure is complicated; even if I succeed, the resulting code will be hard to maintain and vulnerable to future changes by Sisense.

Has someone done this before, either using DOM-manipulation or a better way?
