I don't think there is a row header property like the column header, you can leave the first row blank and white the headers in the first column so simulate it. You can create a simple subvi which takes a reference to the control and a string array and in a for loop set the string value of cell (0, i) to the value of the string[i] array input. As far as I know there is not a row header like there is a column hearer though. This is typical in spreadsheets where the rows are indexed and not named but the columns are.
