+    Patch the qualname for functions that are directly added to Axes.
+
+    Some Axes functionality is defined in functions in other submodules.
+    These are simply added as attributes to Axes. As a result, their
+    ``__qualname__`` is e.g. only "table" and not "Axes.table". This
+    function fixes that.
+
+    Note that the function itself is patched, so that
+    ``matplotlib.table.table.__qualname__` will also show "Axes.table".
+    However, since these functions are not intended to be standalone,
+    this is bearable.
