For example: If we want to calculate the third line of the fourth column in the third line of the second column and the third column of the product, then the third line of the second column is b3, the third column is c3, the formula is b3 * c3, enter the completion of the point "OK" or enter. In the third row of the fourth column will display the results of the calculation. That is to say, the order of the columns are: a, b, c, d ..., the order of the rows are 1, 2, 3, 4 ...... Calculations in the staggered table is also the same; for example: (the picture is not displayed, you can click, open the full picture)
