Type alias ValueSetter<T>

Type declaration

• • (row, value): boolean | void

  • Writes an edited value of a calculated column back into the row (ColumnDefIf.valueSetter). Without a setter a calculated column cannot be edited. Return false to reject the value.

    Parameters

    • row: T

    • value: unknown

    Returns boolean | void

    Example

    // "total" is price × quantity – editing the total changes the price
    const setTotal: ValueSetter<Item> = (row, value) => {
      const total = Number(value);
      if (!Number.isFinite(total) || !row.quantity) return false;
      row.price = total / row.quantity;
    };
