A wiki table rendered inside a cell is very different from the outside a cell

If I, as a user, try to render a wiki table inside a table cell, all the wiki table cells length appear shrinked, regardless of the available space.
However, if the same table is rendered outside a table cell, all the wiki table cells length appear proportinal to the available space.

In order to replicate this problem, follow these instructions:

1. Create a Cucumber Test Issue, and populate the Cucumber Definition as follows:

   | scenario_id | description | useralias | role | create | result | subjectA | role2 | create2 | subjectB | role3 | create3 | page_name | beforesearchA | beforesearchB | searchfield | aftersearchA | aftersearchB |
   | PAT-1854-01 | support user views id patient profile | autosupport | support | true | success | sorting1 | patient | true | sorting2 | patient | true | Patient Profile | exists | exists | Proteus Id | exists | not exists |

2. Export it using the attached Template, and check the differences between the wiki table inside a cell and outside a cell.
