TableView and TableColumns

[Craig Ziesman <cz...@mac.com>]

Hello. This is my first post to the group.

I am trying to build a TableView component, but I want to control the layout of the column headings. I tried passing the "element" binding to my TableColumns component, but nothing changed in the display. Upon further investigation, I found that the <TH> element that gets rendered ultimately wraps a <TABLE align="center"> tag way down in the guts of SimpleTableColumnFormComponent.html, which doesn't work because I want my headings left-justified.

Before I starting hacking through the underbrush to make this work, has anybody run into this before? If not, any suggestions on how to achieve what I want? I saw the getColumnRender() method in ITableColumn, but it's not clear to me how to subclass these components when all I want to do is change the .html file associated with the component.

Thanks,
Craig Z.

I don't have our code immediately handy, but I disliked the nested 
tables in the headers too (but be aware that the sorting graphic 
appears there too) and overrode the templates used.  Simply copy the 
existing templates to your WEB-INF/classes directory in the same 
directory structure that they live within the contrib JAR and then 
tweak them how you like.  You can do this without touching any Java 
code or anything else.  We've overridden a few of these templates like 
this and it works great.

You can, if you need more programatic control, change the column 
renderer by hacking underneath.
