I've a datagrid with three columns:
{field:'file',title:'File',width:228},
{field:'percent',hidden:true},
{field:'progress',title:'Progress',width:100}
.
The progress column contains a progress bar composed with some <div> and CSS to show the percent complete, but the numeric percent is stored in the hidden percent column.
Can I somehow make progress sortable, but actually sort by percent?
