Ich verwende FPDF, um Tabellen zu rendern, die innerhalb des HTML-Inhalts sind. So wie ich Tabellen rendern wollte, bekam ich diese link, um die Tabelle zu rendern. Die Sache ist, ich habe zwei Tabellen nacheinander im HTML und ich kann es nicht trennen, da der Inhalt durch WYSIWYG Editor kommt. Hier für den ersten Tisch funktioniert es gut. Aber für die zweite Tabelle funktioniert es überhaupt nicht. Ich habe alle Markups überprüft und alles sieht gut aus.FPDF WriteHTML() mehrere Tabellen-Rendering zeigt nur die erste korrekt
html_table.php ist wie dieser

und die index.php ist wie folgt

';

Kann mir jemand sagen, wie dieses Problem zu lösen? Jede Hilfe und Vorschläge werden wirklich spürbar sein. Dank
