Recognizing Names as Addressing
You can use cells with text to refer to the rows or to the columns that contain the cells.
In the example spreadsheet, you can use the string \<item type=\"literal\"\>'Column One'\</item\> in a formula to refer to the cell range \<item type=\"literal\"\>B3\</item\> to \<item type=\"literal\"\>B5\</item\>, or \<item type=\"literal\"\>'Column Two'\</item\> for the cell range \<item type=\"literal\"\>C2\</item\> to \<item type=\"literal\"\>C5\</item\>. You can also use \<item type=\"literal\"\>'Row One'\</item\> for the cell range \<item type=\"literal\"\>B3\</item\> to \<item type=\"literal\"\>D3\</item\>, or \<item type=\"literal\"\>'Row Two'\</item\> for the cell range \<item type=\"literal\"\>B4\</item\> to \<item type=\"literal\"\>D4\</item\>. The result of a formula that uses a cell name, for example, \<item type=\"literal\"\>SUM('Column One')\</item\>, is 600.

If you want a name to be automatically recognized by Calc, the name must start with a letter and be composed of alphanumeric characters. If you enter the name in the formula yourself, enclose the name in single quotation marks ('). If a single quotation mark appears in a name, you must enter a backslash in front of the quotation mark, for example, 'Harry\'s Bar'.
