<p>
Mobile devices don't display them nicely.
Most tables can be converted into a list:
</p>

<table>
  <tr>
    <th>OS</th><th>Init</th><th>Pkg</th>
  </tr>
<tr>
<td>Fedora</td><td>systemd</td><td>dnf</td>
</tr>
<tr>
<td>Slackware</td><td>BSD-style</td><td>slackpkg</td>
</tr>
<tr>
<td>Gentoo</td><td>OpenRC</td><td>emerge</td>
</tr>
</table>

<p>Can be represented as a list. In YAML terms, this is a <em>sequence</em> of <em>mappings</em>.
</p>

<ul><li>Fedora
<ul><li>Init system: systemd</li>
<li>Package manager: dnf</li>
</ul></li>
<li>Slackware
<ul>
<li>Init system: BSD-style</li>
<li>Package manager: slackpkg</li>
</ul></li>

<li>Gentoo
<ul>
<li>Init system: OpenRC</li>
<li>Package manager: emerge</li>
</ul></li>
</ul>

<p>A table doesn't always translate exactly to a list, but it probably can be restructured. </p>

<table>
<tr>
<th>OS</th><th>Open source</th><th>Landed on Mars</th></tr>
<tr>
<td>Linux</td><td>Yes</td><td>Yes</td>
</tr>
<tr>
<td>BSD</td><td>Yes</td><td>No</td>
</tr>
<tr>
<td>macOS</td><td>No</td><td>No</td>
</tr>
</table>

<p>Could be written like this instead:</p>

<p>Linux and BSD are open source operating systems, while macOS is not. Of these POSIX-compliant systems, only Linux has landed on Mars so far.</p>

<p>That's pretty casual and loses the visual impact of a table or a list. So alternately, you could summarize what's common and highlight differences:</p>

<p>
There are a few Linux systems on Mars.
Neither BSD or macOS have yet landed on Mars.
</p>

<ul>
<li>Linux and BSD are both open source.</li>
<li>macOS is based partially on open source and includes components from the BSD, KDE, GNU, and other projects.</li>
</ul>
