Ignore delimiters within line elements in tables

Commit d812466 had an issue where, when scanning for unstyled pipe
characters within a table row, any delimiter found within a line
element would be treated as the start of a new line element, even
though line elements cannot be nested. The correct behaviour is to
ignore delimiters for all other line elements while inside a line
element.
