It's work, but only if i change the script in the library.
If i create a button in my stack, paste the script of button "Default Header" of stack "revDataGridLibrary" in it, change the script, and set the dgProp of the dataGrid to this button, the htmltext doesn't work : in the label of a column is see "<img src=200656>my label" and my image and the label.

Then, i want to use my own "international" sort (but i saw there is a lesson about this).
The built-in international sort forgot "œ, é, à...." i hope rev 4.5 come with a real international sorting !
