using datatables 1.10.25
https://jsfiddle.net/fredlllll/6vxpuLsy/11/ here is a minimum working example.
i have a simple table that has a colspan=2 in the header. When running datatables on it, i get an error in the console "headercells[i] is undefined". this leads to the pagination not being added till i click on one of the headers. furthermore i cant sort by the colspanned column
meanwhile the documentation boasts that datatables is fully compatible with row and colspan https://datatables.net/examples/basic_init/complex_header.html
seems like this simple case slipped through the cracks...

just checked multiple versions and this breaks in all of 1.10.x and even in 1.9.x
There is a key sentence in the example you linked:
Your one
theadwith colspan doesn't meet this criteria. Click on the HTML tab of the example to see how that table is setup. You will need a second header row that has athfor each column for the event listeners.For example:

so there is no way to make it look like a normal column? cause this 2 level header thing is not what my client wants as design
I would look at using
columns.renderto combine the image with the coin, like this example. Maybe this will get you started:https://jsfiddle.net/uhqn4azd/
You might need to add some styling to center the coin name.
