C-h v org-table-transpose-table-at-point RET

will tell you if the function is loaded, marked for autoload but not
loaded yet, or is unknown.

The fact that completion did not show it means that the file containing
it is not loaded and there is no autoload for this function.

Your only recourse then is to load the file by hand

M-x load-library RET org-table RET

assuming that you know which file it is, or use one of the org-table
functions that *are* marked for autoload. You can use completion to find
out those

C-h f org-table-TAB

and then call one. Using the function will autoload it and bring in the
rest of the functions defined in the file with it.
