I've not used the Febooti automation program and don't quite know what you consider a cropped column header. Could you provide screen captures of what you see without using Febooti and what you are seeing using Febooti? If you feel uncomfortable doing so with your data set, use a data set that ships with Tableau.
If things work fine in Tableau, you should check with Febooti to see if there are similar issues and resolutions using their program for the issue is not with Tableau. For example, you may wish to check out http://www.febooti.com/support/faq/iezoom/print-web-cut-off-header-footer.html.
Hope this helps,
