When I insert a JIRA Issue/Filter macro on a Confluence page as a table, a long text is not wrapped and the width of the column is fixed by the length of the text.
If the the page is then exported to Word or PDF, the table either runs off the page (Word) or columns are missing entirely (PDF).

Update: The Change History macro is causing this issue. After removing the Change History macro from the Confluence page, the text is wrapping as expected and all the table columns I have defined are visible on the page even after exporting to Word and PDF formats.

Note: Depending on the number of columns defined,JIRA Issue/Filter Macro tables are prone to overflow the page when exported.

Workaround

Reduce the number of columns on the JIRA Issues macro to fit on the page on Confluence without needing to scroll to right.
