   *     worksheet object.
   *   - columns (string[]): An indexed array of columns.
   *   - keys (string[]): A list of columns that are giving the primary key.

   *     starts. It's the value of the spreadsheet row that contains the table
   *     header. If the table row is the first this should be 1. A value of 3
   *     would mean that the table header is on the third row.
   *   - row_index_column (string): The row index column name. The 'row index
   *     column' is a pseudo-column, that not exist on the worksheet, containing
   *     the current index/position/delta of each row. The caller can pass a
   *     name to be used for that column. If a name was passed, that column will
   *     be also outputted along with the row, in ::current(). The same name can
   *     be passed also in 'keys' list. In that case the row index will be or
   *     will be part of the primary key.
