Won't work because make-symbol returns an uninterned symbol (which has
the print name "insert-html-table", but not the meaning of the
previously interned symbol with the same name):

    make-symbol is a built-in function in `C source code'.
    (make-symbol NAME)

    Return a newly allocated uninterned symbol whose name is NAME.
    Its value and function definition are void, and its property list
    is nil.

Instead you need to use intern:

    intern is a built-in function in `C source code'.
    (intern STRING &optional OBARRAY)

    Return the canonical symbol whose name is STRING.
    If there is none, one is created by this function and returned.
    A second optional argument specifies the obarray to use;
    it defaults to the value of `obarray'.
