HTMLTableColElement: chOff property
Deprecated
Avoid using this feature in new projects. Some table styling attributes have no effect. They are superseded by CSS. This feature may be a candidate for removal from web standards or browsers.
The chOff property of the HTMLTableColElement interface does nothing. It reflects the charoff attribute of the <col> element.
Note: This property was designed to participate in an ability to align table cell content on a specific character (typically the decimal point), but was never implemented by browsers.
To achieve such alignment, watch for the support of a string value with the text-align CSS property.
