<p><em class="dfn">Fields</em> are a more general way of laying out tabular data. A field
is defined as the data between a pair of <em class="dfn">delimiting characters</em>.
It contains substrings that are separated by <em class="dfn">padding characters</em>.
The width of a field is the distance on the <em class="emph">input</em> line from the
position where the field starts to the next tab stop. A padding
character inserts an adjustable space similar to TeX’s <code class="code">\hss</code>
command (thus it can even be negative) to make the sum of all substring
lengths plus the adjustable space equal to the field width. If more
than one padding character is inserted, the available space is evenly
distributed among them.

<p>Define a delimiting and a padding character for fields. If the latter
is missing, the padding character defaults to a space character. If
there is no argument at all, the field mechanism is disabled (which is
the default). In contrast to, e.g., the tab repetition character,
delimiting and padding characters are <em class="emph">not</em> associated with the
environment (see <a class="pxref" href="Environments.html">Environments</a>).
