I've asked for this before, but ended up doing things manually. See my
DB_DO_FB_Frontend code:
http://pear.reversefold.com/horde/c...B_DataObject_F=
 ormBuilder_Frontend%2FFrontend%2FShowTab
le.php#115

addColumn itself does not do this. The columns are auto-created only
if there are no columns added. See Structures/DataGrid/Renderer.php
function _setDefaultHeaders().

That's the same reason I wanted to do it, see the other addColumn
calls in the above code. IMHO it's easy enough to manually add the
columns, so I didn't push further. However, I would think it would be
pretty easy to make the auto-column creation happen if the
generate_columns option is set in the DataSource. The quesiton then is
whether they should be before or after the manually added columns....

Why not come up with some functions called "insertColumnBefore" and
"insertColumnAfter".  Kinda like what was added to QuickForm.  Standard
"addColumn" parameter list but with an extra one for placement.  Or an
"appendColumn" that wouldn't interfere with the auto-generation system
and allow for trailing columns (which is where I put my "tools" column).

Maybe if I find some time...  :)

Sorry for not implementing this, I must have lost your request in the
black hole that is my inbox.

Can you or someone add this to the bug system?  I want to try to get a
new release out soon, so if it is in the bug system it will get included
in the next release.

Thanks
Andrew

Sure.. In progress.
