Here I try to address bug where content of table overflows it's width (hacker news is an example of such site) by reimplementing some parts of table formatting context. Now TFC implements first steps of: https://www.w3.org/TR/css-tables-3/#table-layout-algorithm but column width and row height distribution steps are still very incomplete.
