Sorry, caught up on my bugmail after our IRC discussion and just saw your question here. :) (In reply to Alexandre Poirot [:ochameau] from comment #5) > > If we want to keep the `position:absolute` hack for the time being, > The usage of `position:absolute` is related to the `overflow: auto`. > It intends to implement a scrollable table. > > Using `overflow:auto` on a `<table>` doesn't work. It doesn't produce a scrollable table, instead, the table expands to the full height of all its rows. Do you really need it to be `position:absolute`, though? It sounds like maybe you just need `overflow:auto` which works on blocks though apparently doesn't work on tables. And `position:absolute` is a complex thing which had the **side effect** of making this element into a block and thereby making `overflow` do what you expected -- but really maybe the `display:block` is all that you need (no `absolute) for the scrollable element? > Daniel, Do you think you could be able to know why or what causes the full table to repaint when adding a new row? I think we sorted this out over IRC.
