         * The `mct-autoflow-table` directive specifically supports
         * autoflow tabular views; it is not intended for use outside
         * of that view.
         *
         * This directive is responsible for creating the structure
         * of the table in this view, and for updating its values.
         * While this is achievable using a regular Angular template,
         * this is undesirable from the perspective of performance
         * due to the number of watches that can be involved for large
         * tables. Instead, this directive will maintain a small number
         * of watches, rebuilding table structure only when necessary,
         * and updating displayed values in the more common case of
         * new data arriving.
