🔢 Format table HTML in documentation

[agoose77]

This tiny PR just applies an HTML formatter to the table HTML, so that it is more readable (less wrapping)

Before:

<table>
<tr><th rowspan="2">Projection</th><th colspan="3" align="center">Area in square miles</th></tr>
<tr><th align="right">Large Horizontal Area</th><th align="right" style="background: -webkit-linear-gradient(20deg, #09009f, #E743D9); -webkit-background-clip: text; -webkit-text-fill-color: transparent;">Large Vertical Area</th><th align="right">Smaller Square Area<th></tr>
<tr><td>Albers Equal Area</td><td align="right">7,498.7</td><td align="right">10,847.3</td><td align="right">35.8</td></tr>
<tr><td>Web Mercator</td><td align="right">13,410.0</td><td align="right">18,271.4</td><td align="right">63.0</td></tr>
<tr><td>Difference</td><td align="right" style="background-color: red;color: white">5,911.3</td><td align="right">7,424.1</td><td align="right">27.2</td></tr>
<tr><td><bold>Percent Difference</bold></td><td align="right" style="background-color: green;color: white">44%</td><td align="right">41%</td><td align="right">43%</td></tr>
</table>

After:

<table>
   <tr>
      <th rowspan="2">Projection</th>
      <th colspan="3" align="center">Area in square miles</th>
   </tr>
   <tr>
      <th align="right">Large Horizontal Area</th>
      <th align="right" style="background: -webkit-linear-gradient(20deg, #09009f, #E743D9); -webkit-background-clip: text; -webkit-text-fill-color: transparent;">Large Vertical Area</th>
      <th align="right">Smaller Square Area
      <th>
   </tr>
   <tr>
      <td>Albers Equal Area</td>
      <td align="right">7,498.7</td>
      <td align="right">10,847.3</td>
      <td align="right">35.8</td>
   </tr>
   <tr>
      <td>Web Mercator</td>
      <td align="right">13,410.0</td>
      <td align="right">18,271.4</td>
      <td align="right">63.0</td>
   </tr>
   <tr>
      <td>Difference</td>
      <td align="right" style="background-color: red;color: white">5,911.3</td>
      <td align="right">7,424.1</td>
      <td align="right">27.2</td>
   </tr>
   <tr>
      <td>
         <bold>Percent Difference</bold>
      </td>
      <td align="right" style="background-color: green;color: white">44%</td>
      <td align="right">41%</td>
      <td align="right">43%</td>
   </tr>
