* column label enclosed between double quotation marks, such as |
| 25 |
* "Age" or "Yield," or a number (without quotation marks) that |
| 26 |
* represents the position of the column within the list: 1 for |
| 27 |
* the first column, 2 for the second column, and so on. |
| 28 |
* @param mixed[][] $criteria The range of cells that contains the conditions you specify. |
| 29 |
* You can use any range for the criteria argument, as long as it |
| 30 |
* includes at least one column label and at least one cell below |
