<p>Organization and utility have more value than prettiness.</p>

<p><strong>Use inline code formatting</strong>, as in</p>

<pre><code>Header 1    Header 2     Header 3
123.45      -6.7         abc
8           9.0          xyz
</code></pre>

<p>This is simple (usually a copy-and-paste operation followed by a click of the <code>Preformatted text</code> control) and useful (because readers can copy the data in a format suitable for input with most software).</p>

<p><strong>$\TeX$ markup is an option</strong> where formatting of the data is essential (which is almost never).  $\TeX$ includes a myriad ways to tabulate things, as in</p>

<p>$$\begin{align}
\text{Header 1}\qquad &amp;\text{Header 2}\qquad &amp;\text{Header 3} \\
123.45\qquad &amp; -6.7\qquad &amp; \text{abc} \\
8\qquad &amp;9.0\qquad &amp;\text{xyz}
\end{align}$$</p>

<p><strong>Avoid posting data as images</strong> (unless the images, as bitmapped rasters, <em>are</em> the data): there is no straightforward way to use such code without manually transcribing it.</p>

<p><strong>Please do not post large amounts (multiple pages) of data</strong>: either strip down the data to a smaller example (which is <em>much</em> preferred) or post the full dataset elsewhere and provide a link (which is discouraged because the link may eventually rot).</p>
