Question

I am creating a report with some data like below: 我正在使用以下数据创建报告：

A    2    1    2    1
B    4    5    6    8

For the above data i would like to summarize each column and each row totals like below. 对于以上数据，我想总结每一列，每一行总计如下。

    1/1  1/2  1/3  1/4 
A    2    1    2    1    --> 6(addition of all values)

B    4    5    6    8    --> 23

     6 6 8 9   29

Please suggest how to achieve this using pentaho report designer. 请提出如何使用pentaho报表设计器来实现此目的。

We need to know more of your data but it's a classic sum in mysql : 我们需要了解更多您的数据，但这是mysql中的经典数据：

SELECT column, SUM(column) FROM table
GROUP BY column
