Title: Display arrow in gridview header only if the column is sortable.

I created a widget based on the TbGridview, not sortable but with links in headers and arrows was displayed.
The selector of the css style which display an arrow on sortable column match link **a**, but a sortable column contains a link with the class **sort-link**.
I modified the selector to correct the issue.
