Expand child rows which contain the same number of columns like parent row

AlbionAlbion Posts: 2Questions: 2Answers: 0

have a table which contains parent and child rows. initially, i want to hide child rows when i click on parent row need to expand child row.
here's what I tried: https://jsfiddle.net/Albion87/tnozsp5s/35/

[This example has another issue:] which is if I freeze the first column I won't be able to sort horizontally, if I disable freezing first column then I can sort horizontally.

any idea to solve this issue
