UPDATE: Solution found
UPDATE: No proposed answers. No solution found on my end. Anybody?
I am using javascript to match the width of columns in two seperate tables (using this to create a scrollable, sticky header table. If the data is all visible (no overflow), the method works fine. If the tables do overflow, however, the table columns do not align. I have a debugging stream that shows the offsetWidths are still returning the same numbers. Any ideas on why this is happening?

Table-layout for both tables needs to be fixed in order to adjust the size of the cells and have it affect the table as a whole. By default, this is auto, and the table adjusts to the size of it’s container/contents of its cells.
