I've restructured this example a bit.
Things to note:
* You cannot have equations spanning multiple table columns.
Each equation has to be self-contained within a table cell.
To make the parts of the equations line up, I split the
equations up into parts for the different columns.
* Whitespace is significant in tables, but is normally not
significant inside equations. Even though the column
descriptor says "l0", there is space after it because
that space is part of the cell content (spaces around
the column delimiter "@").
* Keep equations as simple as possible. GNU eqn gets
spacing mostly correct by itself. Don't space things
manually except in specific circumstances.
* eqn recognizes defined names only if they are surrounded
by whitespace (or adjacent to braces). This is important
for getting function names (sin, cos, ...) typeset correctly.
* the ... sub "" ... is a hack to make the root symbol
become a bit larger.
