Subject Re: center the text of header columns of tableView
Date Thu, 05 Aug 2010 11:55:48 GMT
The reason it is done automatically is because a developer may want to combine both icon-only
and text headers in a table view, but TableViewHeader only supports only a single header data
renderer that is common to all headers. As a result, the renderer needs to make some assumptions
about how the data should be presented. 

Perhaps it would be better to allow the caller to define the header data renderer on a per-column
basis, in the TableView.Column class. The header data itself lives in the column, so arguably
the header data renderer should go there as well.

cc'ing the dev list for comments.

display (only icon : centered-aligned, icon + text or text only : left-aligned) but if the
user defined the value horizontalAlignment via the styles property that use property value
