Each column has same width in a wide table regardless of the contents on exported PDF

Summary

Thanks to the fix for CONFSERVER-34390, wide tables are not cut of in an exported PDF. However, each column has same width in the table regardless of the contents instead.

We could also see the same behaviour in cases that we applied the workaround suggested in CONFSERVER-34390 to previous versions of Confluence.

table.confluenceTable {
    width: 100%;
    table-layout: fixed;
}

Steps to Reproduce

1. Create a new page
2. Create a table with at 15 columns (number of rows shouldn't matter)
3. Paste a long string into one of the columns and short strings into the others
4. Save the page
5. Export to PDF

Expected Results

Each column width should be based on the contents.

Actual Results

Each column has same width regardless of the contents.

• Table on browser
  
• Table on the exported PDF
  

Note

CONFSERVER-34390 was avoidable by using a workaround.
The eventual fix was to add the width: 98% !important; line when the column width is greater than 80 characters (and some code to look for this and test it) to the confluence-pdf-export-plugin

table.fixedTableLayout {
    table-layout: fixed;
    width: 98% !important;
}

This only affects tables that would otherwise go wider than the exported PDF page. Narrow tables are not affected by this. 
Tables set as either Fixed or Responsive are affected.

Workaround

You can get tables to export better by setting the PDF CSS as

table.fixedTableLayout {
table-layout: auto !important;
width: auto !important;
}

You can set this by Space or Globally.

Space

1. Go to Space Tools > Look and Feel
2. Go to PDF Stylesheet
3. Click Edit
4. Add this CSS

   table.fixedTableLayout {
   table-layout: auto !important;
   width: auto !important;
   }
   

1. Click Save

Globally

1. Go to > General Configuration > PDF Stylesheet
2. Click Edit
3. Add this CSS

   table.fixedTableLayout {
   table-layout: auto !important;
   width: auto !important;
   }
   

1. Click Save

View source and print as PDF

1. Another workaround is to view the Page Source and print the page as PDF.
2. The PDF will be what you see on the page.
