When using HTML in your Table Maker content it’s important to be sure that any quotation marks used in HTML attributes are inch-marks and not smart-quotes.
Smart-quotes appear as italicized quotation marks.
Inch-marks appear as straight quotation marks.
Although the visual difference between smart-quotes and inch-marks is subtle, if smart-quotes are used they will affect the appearance and proper functioning of the table.
Note: The replacing of inch-marks with smart-quotes sometimes occurs when copying and pasting content into the table rather than typing it in manually.
