ADF af:column width attribute

Question

Hello,
I'm trying to expand the width of columns inside an af:table component so they stretch automatically according to the parent's size. I have tried all ways but columns always get set the default 100px width. The only way to make it stretch is using the af:table attribute columnStretching="last", but it only stretches the last column, not the whole table.
Anyone ever had the same problem?
Thanks!

Short answer: Sorry, you can't.
If you look at the generated HTML code, you'll see that a table with 2 columns in your code does not end up creating a table and 2 columns in the html, it ends up far more complicated.
In fact if you set the width to something like 555 and then search on 555 in the code, you won't even find it. Because the width are calculated from the server side.
So while it may be possible to override this, and to set the width to a percent (And to do so I would recommend investigating using styleClass and inlineStyle to set the width)
To quote from the oracle docs
The data cells in the table rendered by<af:column> tags can be styled by using styleClass and inlineStyle attributes.
The column header cells can be styled using headerClass attribute.
Please note that changing padding and border settings through these attributes is very dangerous.
We calculate widths on the server side and expect padding and border attributes to be specified as skinning properties.
If they get overridden, the aligment[sic] of the table cells might be messed up.
