CKEditor doesn't keep the alignment or border of a table from an OpenOffice document

Steps to reproduce:

1. Create a new xwiki page
2. Copy the content of the attached file TestOpenOffice.odt
3. Edit the page with CKEditor
4. Press the icon "Paste from Word"
5. Click on "Don't allow" when the "Do you want to allow this webpage to access your Clipboard" message box appears
6. Paste the copied content in the new box
7. Click on the OK button
8. Observe the tables
9. Click Save & View
10. Observe the tables

Expected results: The tables alignment and borders are the same as the document.

Actual results: There is no center alignment kept and the borders don't appear.
In view mode the second table, that had a 2.50pt border in the document, has no borders and instead has blank spaces between the rows.
