PDF output from Tableau is missing column headers, headings or other parts of the report or dashboard. This issue can occur with Tableau Web Server, Tableau Desktop, from Subscriptions and from DSA AD or DSA Cloud AD.
This usually is seen when the report or dashboard is too wide for normal page size output. The solution is a combination of 1) making the page less wide by adjusting the width of columns and/or 2} using PDF settings to produce wider output.
