      ConfigBuilderInterfaces.MultiTableDataColumnStep4 multiRow()
      Defines that the data for a single record can be spread across multiple rows.

      This property must be set if the same column is mapped to multiple attributes (with filter column(s), see example below) or if this is a collection attribute and you want to allow AND for two conditions of the same attribute (e.g., color=blue AND color=red.

      Example: 

        +------+------------+-------------+
  | ID   | ENTRY_TYPE | ENTRY_VALUE |
  +------+------------+-------------+
  | 8599 | MODEL      | X4886       |
  +------+------------+-------------+
  | 8599 | BRAND      | QUACK       |
  +------+------------+-------------+
  | 8599 | COLOR      | BLACK       |
  +------+------------+-------------+
  | ...  | ...        | ...         |
      Let's say we want to query model=X4886 AND brand=QUACK.

      Obviously, from the table above you cannot query ... WHERE ENTRY_TYPE='MODEL' AND ENTRY_VALUE='X4886' AND ENTRY_TYPE='BRAND' AND ENTRY_VALUE='QUACK'

      The problem is that the first condition would fix the row, so the second condition will never become true (accidental row-pinning).

      With the multi-row you tell the query builder about this problem and enforce a different query style.

      Returns:
      builder
