I use the column view to show my estimated effort for my tasks, and work. It is very useful to schedule the tasks of the day. But I would like to see the remaining effort of each task, i.e., (estimated effort) - (clocksum) instead of the estimated effort. Is it possible to add a column with the Remaining effort instead of the Estimated effort?

You would have to use the following specifier %(expression) from the documentation of org-agenda-prefix-format.
the expression would calculate the difference between the clocksum and the effort estimate. Here's how you would write it:
%(org-minutes-to-clocksum-string (abs (- (org-clock-sum-current-item) (org-hh:mm-string-to-minutes (or (org-entry-get (point) \"Effort\") \"0:00\")))))
What's happening here is that we're getting the estimate effort of the task at point in HH:MM format and then converting it to minutes to perform the subtraction with the clocksum which is already in minutes. After that we apply the abs function to make sure we get a positive number of minutes. Finally, we convert the minutes to HH:MM format.
Here's an example on how you would use it in org-agenda-prefix-format:
(org-agenda-prefix-format " %i %-15:c [%(org-minutes-to-clocksum-string (abs (- (org-clock-sum-current-item) (org-hh:mm-string-to-minutes (or (org-entry-get (point) \"Effort\") \"0:00\")))))] ")
