Problem with table heading ending in a pipe

[bmomjian]

With asciidoctor 1.5.2, if the last cell of a table heading ends with a pipe, the rendered HTML assumes the first data row is part of the heading, e.g. this:

    [options="header",cols=">l,<l",frame="none"]
    |====
    ^l|stuff ^l|abc\|X
    |2 |hello\|
    |3 |hello
    |====

yields a correct HTML heading of:

    stuff   abc|X

which is good, but if you remove the "X" from the asciidoc heading, the
HTML output heading is:

    stuff   abc|2

The "X" is gone, but the "2" from the first data row is now in the
heading, and the first and only data row is now:

    hello|3  hello

This sure looks like a bug. Other asciidoc rendering systems do not do this, e.g. https://asciidoclive.com/ . More details can be found here:
