I am currently trying to extend ScrollableTableDataModel to combine scrollable data table and pagination. I have to override the following methods: loadData, getRowCount, getWrappedData, setWrappedData. There is no read docs regarding what these methods are suppose to do. Also, the loadData accepts three arguments, startIndex, endIndex and SortOrder. What should I, if anything, be doing with these values? Could someone provide any documentation or examples on this? I am really lost on this and under the gun.
