Issue

  • The printout of the Wiki pages doesn't print the coloured cells of the tables. Whereas, on the portal, the coloured cells are visible.sample.pngBackgroundcolor1.png

Environment

  • Liferay DXP 7.0

Resolution

  • The reported behaviour can be achieved by overriding the aui.css file as per the business requirement.
  • Below approach can also be followed to achieve the same:
    • At first, we need to either disable the AntiSamy Sanitizer or customize AntiSamy to allow !important. By default AntiSamy Sanitizer is enabled and it will not allow !important. AntiSamy can be disabled or customized by following the below steps,
      • Goto Control Panel-> Configuration.
      • System Settings-> Foundation->AntiSamy Sanitizer.
      • Make the changes as per your requirement and update. 
    • After doing the above changes follow the below steps:
      • Goto Wiki Page
      • Add the tables in the ckeditor.
      • Goto source mode of CKEditor and add "!important" to the source.
        For example:
        <td style="background-color: rgb(99,99,99) !important;">xxx</td>
        (ckeditor.png for reference)ckeditor.PNG
      • Publish and Take the print of this page. The print of the page will display the table with coloured cells.
    • By following the above approach, the coloured cells are printed over the paper
