Represents the property in the row object that represents this column
The consumer-projected template, unwrapped from the signal so it
satisfies the base-class contract (TemplateRef, not Signal).
The table body reads this property inside a template that is already within a change-detection cycle, so the signal will have resolved by the time the first row renders.
A table column whose cell content is defined entirely by the consumer via a projected
<ng-template>.The template receives the row object as the implicit context (
let-row) and the column reference ascolumn– exactly like the built-in columns.Example
