Create the table body row group containing nine table rows with the first cell in each row containing a heading cell displaying the letters A through I. After the initial table heading cell in the first, fourth, and seventh rows of the table body row group, insert three table data cells spanning three rows and three columns each. Altogether, these nine data cells will store the nine 33 boxes that are part of the Sudoku puzzle. In the first row of the table body row, put the three table data cells you entered in the last step in the greenBox, goldBox, and greenBox classes, respectively. In the fourth row, the three data cells belong to the goldBox, greenBox, and goldBox classes. In the seventh row, the three data cells belong to the greenBox, goldBox, and greenBox classes.
