DomPDF does not render table nicely
I use
thead:before, thead:after { display: none; }tbody:before, tbody:after { display: none; }
Almost certainly the issue is your use of Bootstrap. A lot of dompdf issues related to Bootstrap have to do with the :before/:after declarations. I think you can work around the problem in this particular case by applying the following CSS for dompdf:
tbody:before, tbody:after { display: none; }
