Nicht erfasster TypeError: Eigenschaften von undefiniert (Einstellung „_DT_CellIndex“) für Bindungswerte können nicht fe ⇐ HTML

[Guest]

Ich habe unten HTML, für das ich die Fehlermeldung erhalte:
Uncaught TypeError: Eigenschaften von undefiniert können nicht festgelegt werden (Einstellung '_DT_CellIndex')

Code: Select all
