I am using a Javascript method to sync the column widths of two tables. The code for the HTML, CSS, and Javascript are below. The table columns sync fine when the divs are the size of or larger than the tables, but when there is overflow (currently hidden as I'll be adding scrolling later) the table columns do not align. I know that the table widths and column widths are setting fine (I use a logger to check the style.width of each), but they are displaying misaligned by around 12 px.
I've really been baffled by this for a while and could really use the help. Ideas?
