我们有这样的桌子

Cumulative Paid Triangle                                            
               DP 1         DP 2        DP 3        DP 4        DP 5        DP 6        DP 7        DP 8        DP 9       DP 10

对 DP3/DP2、DP4/DP3 等所有列使用公式 DP2/DP1。

从这个公式我们需要得到这样的表格

DP 1    DP 2    DP 3    DP 4    DP 5    DP 6    DP 7    DP 8    DP 9    DP 10
OP 1     3.14    1.54    1.28    1.24    1.21    1.04    1.04    1.06    1.02    -   
OP 2     3.51    1.76    1.55    1.13    1.08    1.13    1.06    1.09    -      
OP 3     4.45    1.72    1.46    1.23    1.04    1.12    1.06    -          
OP 4     4.57    1.55    1.71    1.07    1.09    1.05    -              
OP 5     2.56    1.87    1.36    1.17    1.14    -                  
OP 6     3.37    1.64    1.37    1.24    -                      
OP 7     2.92    1.88    1.44    -                          
OP 8     3.95    2.02    -                              
OP 9     3.62    -                                  
OP 10    -

这是我尝试过的代码：此代码仅适用于有限数量的值（如 DP_1 到 DP_9），但是如果表中有大量值？

        result = cursor.execute("""
        Select
        D1 as DP1,
        D2 as DP2,
        D3 as DP3,
        D4 as DP4,
        D5 as DP5,
        D6 as DP6,
        D7 as DP7,
        D8 as DP8,
        D9 as DP9
        From (
        Select
            DP1,
            DP2,
            DP3,
            DP4,
            DP5,
            DP6,
            DP7,
            DP8,
            DP9,
            DP10,
            DP2 * (DP1 As d1,
            DP3 / DP2 As d2,
            DP4 / DP3 As d3,
            DP5 / DP4 As d4,
            DP6 / DP5 As d5,
            DP7 / DP6 As d6,
            DP8 / DP7 As d7,
            DP9 / DP8 As d8,
            DP10 / DP9 As d9
        from CumulativePaidTriangle
        )""" ```
