[jira] [Commented] (WICKET-4153) The tbody section of a DataTable is empty when no records are returned by the provider.

Matthias Keller commented on WICKET-4153:
-----------------------------------------

This bug just bit me too, we do have a filter and we need the table headers etc to be shown but have a message printed below showing that there were no results. Currently it's not possible to style that table correctly (using borders and border-collapse) since it's no valid XHTML and there's a tbody missing. It would be good if this was fixed for the next version!

> When a DataTable is rendered without records, the tbody section is empty. This violates the html spec.
> From the spec:
> "When present, each THEAD, TFOOT, and TBODY contains a row group. Each row group must contain at least one row, defined by the TR element."
> and
> "The THEAD, TFOOT, and TBODY sections must contain the same number of columns."
