I thought to cross reference I have to enter the starting format as
:ref:`Link Text <CrossReferenceLabel>`
Then use it later on by writing
.. _CrossReferenceLabel:
Like the following.
+-----------+-----------------------------------+-------+
| Number | Animal | |
+===========+===================================+=======+
| 1 | :ref:`Dog <DogLabel>` | |
+-----------+-----------------------------------+-------+
| 2 | Cat | |
+-----------+-----------------------------------+-------+
+-----------+-----------------------------------+-------+
| Dog | Services | |
| | .. _DogLabel: | |
+===========+===================================+=======+
| 1 | Vet | |
+-----------+-----------------------------------+-------+
| 2 | Toy Shop | |
+-----------+-----------------------------------+-------+
The link is created for the Link Text, however the destination doesn't seem to have the cross reference.
