I have a dataset where I have different percentages and I have to pick:
1. If the column value is greater than 80. I have to pick that column
2. If no column value has greater than 80 I have picked the top 2
Below is the sample
| t1 | t2 | t3 | t4 | comment |
| 80 | 2.0 | | 3 | t1 |
| 15 | 8 | 2 | | t1.t2 |
| | 2 | | | t2 |
| | | | | NA |
