Single Arrow Sorting Renderer
This implementation of a SortingRenderer creates an icon based UI for choosing the sorting of a data table.
There is an up-down-arrow icon, if the column is not sorted, but sortable
There is an down-arrow icon, if the data is sorted descending by the current column
There is an up-arrow icon, if the data is sorted ascending by the current column
There is no icon, if sorting is disabled for this column
