// Table Configurations describe how your table should be presented to the user:
// the columns to show, what order to show them, which columns to aggregate, and which columns to graph.
// You may provide a number of columns in your table, but only want to show a subset of them by default so as not to overwhelm the user.
// The user can still open the table properties to turn on or off columns.
// The table configuration class also exposes four (4) columns UI explicitly recognizes: Pivot Column, Graph Column, Left Freeze Column, Right Freeze Column
// For more information about what these columns do, go to "Advanced Topics" -> "Table Configuration" in our Wiki. Link can be found in README.md
