How to avoid the performance cost of overflow:hidden?

[garvasqu]

I have an HTML table that can be more than 1K rows and a dozen or so columns.I want the columns to be a fixed size (controllable by the user) and not grow/shrink either vertically or horizontally. So visually the contents of a particular table cell will be on one line and the overflow gets cut off at the end of the cell.Doing performance analysis in Chrome on a large table the main performance killer is overflow:hidden.I've tried putting the contents of each cell inside of an input, since that would replicate the same visual behavior, but that has a similar performance impact.What do people recommend to improve performance?If necessary I don't have to use a table tag, but would prefer to stick with the table tag if good performance can be achieved.Update 1: I've included a file that demonstrates the performance issue here. Warning the file is pretty massive (25MB) and will slow down your computer. By default the table does not have overflow set to hidden, and once the table has been loaded (can take a while) the browser performance relatively smoothly.However, if you edit the file and uncomment lines 12-15 and then open it. You'll see after loading browser around the table is significantly less responsive.
