1.2. Attributes and attribute quoting

The [table-editor] is capable of accepting a large number of attributes. It uses standard ITL tag quoting, explained in the Interchange Tag Reference.

You can quote with single-quote (<'>), double-quote ("), backtick (`), or pipe (|). Material placed in backticks is run through a safe Perl interpreter. In fact, it is the equivalent of using the [calc] [/calc] tag pair except that contained ITL tags are not interpolated.

Pipe-quoting has the attribute of stripping trailing and leading whitespace; it is often convenient when specifying JavaScript (which uses both single and double quotes frequently) in the various *_extra parameters.
