Question: mpdf do not break table?
Answer: If a table has the property page-break-inside: avoid and will not fit on the page, mPDF tries to shrink it to fit - up to a maximum “shrink-factor” set by the variable $mpdf->shrink_tables_to_fit - default is 1.4 (i.e. about 70% original size). If this still does not fit, it moves it to the next page.
