FixedColumns example

# Preamble

A typical interaction to want to perform with a fixed column, is an index column. A method for how this can be achieved with FixedColumns is shown in this example, building on the index column example for DataTables. Also shown in this example is how the fixed column can be styled with CSS to show it more prominently.
