This has been an on-going issue for 8 years from what I can see and the topics closed when no resolution was forthcoming.
A table display needs to have the table headers row locked in position !!!
There have been some work arounds but they dont always work if others CSS or Max Width is used.
To me this is a major fault.
Table headers should be fixed in place, not overwritten by data as you scroll through. What gives KNACK - cant it be done ?
If so tell us it can’'t be done or please prioritise remedying this.
