You can refer to Removing the Sort Icon | Tableau Software
There is no easy way to do this right now. Here is an Idea that you can also Vote Up to see if Tableau will implement this feature in upcoming versions: Ability to Disable the One-Click Sort
Hope this helps.
thanks Ankit, i dont know if we are talking same thing. i dont care about showing the icon, my goal is to not allow user to sort by the row header. is this possible? based on your links is doesnt seem possible to disable (but want to verify since you mentioned 'hiding the icon')
also. some of my tables can be sorted by row header, some cannot, but they are also tables.... is there a logic to why 1 table is sortable by row header and other is not?
the only option i can think of is placing a blank container over the row header in my dash...(but rows canot be highlight)
let me know any other way. thanks for the assistance
