Adds the column configuration to the DataTable's `columns` configuration.
If the `index` parameter is supplied, it is injected at that index. If the
table has nested headers, inject a subcolumn by passing an array of indexes
to identify the new column's final location.
The `index` parameter is required if adding a nested column.

attribute, updating it, and calling
`table.set('columns', _updatedColumnsDefs_)`

table.addColumn('name');
// Inserted after the current second column, moving the current third column
// to index 4
table.addColumn({ key: 'price', formatter: currencyFormatter }, 2 );
// Insert a new column in a set of headers three rows deep. The index array
// translates to
// [ 2, -- in the third column's children
// 1, -- in the second child's children
// 3 ] -- as the fourth child column
