I don't have the answer but I'd wish It has a limt because It won(t make any sense to have a table with 100 measured.
No one will be able to read it and thus it won't help making any valuable decision;which is the main point .
This is because of the resolution of your screen. Drag Emp Name to the left and you will make space for the Total.
Also check out this topic: Table colunm width
Space is already there for Total But i am not able to see total. if i drag total before 31 i can see total but not 31
Then it's obvious that there is not enough space for all of your columns. As suggested, try dragging the first column to the left.
It seems like there is an issue with new version.
You can do it in other way.. Remove the total measure - Adjust the other columns to accommodate total - Now, add total measure again.
It will work for sure.
There is enough space for total you can see in below images.
please see second images column total field .
