Set default value in ColumnFilterWidgets extension?

Hi Tobias,

I am using your ColumnFilterWidgets extension on a table with multiple columns, one of them with different countries. I have managed to get the user to choose what country with the ColumnFilterWidgets plugin and therefor update my table.

How can I now make a country selected by default? How can I set the default value of the drop down list, so it´s a value in the list, or even better (a value from a plugin like Region Detect that I can acess through global variable $rdCountryName) instead of the header tirle of the table?
Best regards,
Alex
