Html export - connect table data with external components

In this sample we have connected the exported table to Google charts with javascript. The table data is imported to EPPlus via the LoadFromDataTable function and the Density column is a calculated table column. The total row of the table is calculated via EPPlus built in Total row functions.

The table has addtional classes from Bootstrap: table and table-sm
