Project Description:
I have an html page with datatable. The table loads data from YAHOO.util.DataSource.TYPE_XML datasource. There are sorting and paging already enabled. I need to add filter functionality:
1.A user fills in filter value (like "To*")
2.Selects by what column he wants to apply the value (like "City")
3.The users press "Refresh" button
4.Some custom request builder should grab that data, append to existing url request, so something like
should be generated. Then table will display data returned back.
