using python 3.8, pandas 1.1.4

I have a dataframe that looks like this

```
id             combination  
1      'A23B14C02R01D05E03F07G07H01I00J02K11L30'
2      'A11B14C02R01D05E03F07G07H01I00J02K11L30'
3      'A30B14C02R01D05E03F07G07H01I00J02K11L30'
...

```

What I want to do is separate combination column into multiple columns that consist one alphabet only.

Desired output should look like this:

```
id    A     B   C   R    D   E    F    G    H    I    J    K    L
1    23    14   02  01   05  03  07   07   01   00   02    11  30
2    11    14   02  01   05  03  07   07   01   00   02    11  30
3    30    14   02  01   05  03  07   07   01   00   02    11  30
...

```

Thanks in advance!
