Column heading width not adjusting properly for JIRA issue macro during PDF Export

Problem

Column heading width not adjusting properly for JIRA issue table during PDF Export, making the headings overlap each other. For text fields, it breaks into multiple lines, for date fields it overlaps the column name.

Environment

Confluence 8.5.5

Steps to Reproduce

1. Create a JIRA Issue/Filter and add a filter to get some results
2. Set it as table and add some columns, with descriptions and some text and some date fields. The bigger the column name more it overlaps
3. Save the macro and publish the page
4. Export it to PDF

Expected Results

The JIRA Issue/Filter table should be rendered properly

Actual Results

Date field headings overlap each other, making them most of the time unreadable.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available.
