21976	Hidden field in TabularInline breaks table layout	yliharma	nobody	"Defining a hidden field in a ModelForm used within a TabularInline breaks the table layout (see screenshot tabular.png): the hidden field label is not present in the <thead> table tag but there is a corresponding <td> tag containing the actual input, resulting in a different number of table columns which breaks the table completely.
