This Chrome DevTools extension adds an extra tab to the Chrome DevTools and will allow you to export any HTML Table in Markdown format.
The latest published version of the extension can be installed from the Chrome Web Store.
To load this extension locally for development, clone the repo to your machine. Visit the Chrome extensions page at chrome://extensions and click the Load Unpacked button. Navigate to and choose this project folder that you cloned. And voilà! The extension will now appear in your browser and DevTools.
Navigate to a page that has an HTML table element. Right click anywhere on the table you would like to export and inspect it in your DevTools. You don't have to select the top <table> element yourself! If you selected anything inside of the table, the extension will find the entire table.
Open the Table to Markdown panel of the DevTools (you may need to click the dropdown to see it). Click the Convert to Markdown button, and your markdown table will appear in the box.
To see an example of how a table will be rendered, let's look at the following table taken from the Scholastic Accolades Wikipedia page.

| Doctor Aristotelis Anima | Johannes Dondus | 1380 |
| Doctor a Doctoribus | Antonius Franciscus | 1528 |

Most Markdown table parsers do not support header-less tables. To compensate for this, this extension throws in a blank header row. For example, take the following table (taken from the NBA Most Valuable Player Award Wikipedia page).
<tr>
<td style="background-color:#CFECEC; border:1px solid #aaaaaa; width:6em; color: #535056;">^</td>
<td>Denotes player who is still active in the NBA</td>
</tr>
<tr>
<td style="background-color:#FFFF99; border:1px solid #aaaaaa; width:6em; color: #535056;">*</td>
<td>Inducted into the <a title="Naismith Memorial Basketball Hall of Fame">Naismith Memorial Basketball Hall of Fame</a></td>
</tr>
<tr>
<td style="background-color:#FFE6BD; border:1px solid #aaaaaa; width:6em; color: #535056;">†</td>
<td>Denotes player whose team won championship that year</td>
</tr>
<tr>
<td>Player (X)</td>
<td>Denotes the number of times the player had been named MVP at that time</td>
</tr>
<tr>
<td>Team (X)</td>
<td>Denotes the number of times a player from this team had won at that time</td>
</tr>
This table will be rendered in Markdown like this:
| | |
|------------|--------------------------------------------------------------------------|
| ^ | Denotes player who is still active in the NBA |
| * | Inducted into the Naismith Memorial Basketball Hall of Fame |
| † | Denotes player whose team won championship that year |
| Player (X) | Denotes the number of times the player had been named MVP at that time |
| Team (X) | Denotes the number of times a player from this team had won at that time |
HTML tables sometimes leave off empty cells in the final column, like this table about medieval accolades.
<tr>
<th>Accolade</th>
<th>Name</th>
<th>Death</th>
<th>Translation/Notes</th>
</tr>
<tr>
<td><i>Apostolus</i></td>
<td>St. <atitle="Paul of Tarsus">Paul</a></td>
<td>67</td>
<td>Due to his preeminence among the Letters of the Apostles within the Bible</td>
</tr>
<tr>
<td><i>Commentator</i></td>
<td><a title="Averroes">Averroes</a> (Ibn Rushd)</td>
<td>1198</td>
</tr>
<tr>
<td><i>Magister sententiarum</i></td>
<td><a title="Peter Lombard">Peter Lombard</a></td>
<td>1160</td>
</tr>
<tr>
<td><i>Philosophus</i></td>
<td><a title="Aristotle">Aristotle</a></td>
<td>BC 322</td>
</tr>
<tr>
<td><i>Propheta</i></td>
<td><a title="David">David</a></td>
<td>BC 10th century</td>
<td>Due to his authorship of the <a title="Psalms">Psalms</a></td>
</tr>
<tr>
<td><i>Theologus</i></td>
<td><a title="Augustine of Hippo">Augustine of Hippo</a></td>
<td>430</td>
</tr>
It will be rendered in Markdown with the cells missing as well. Markdown parsers usually handle this gracefully and render the table with those cells blank.
| Accolade | Name | Death | Translation/Notes |
|-----------------------|----------------------|-----------------|---------------------------------------------------------------------------|
| Apostolus | St. Paul | 67 | Due to his preeminence among the Letters of the Apostles within the Bible |
| Commentator | Averroes (Ibn Rushd) | 1198 |
| Magister sententiarum | Peter Lombard | 1160 |
| Philosophus | Aristotle | BC 322 |
| Propheta | David | BC 10th century | Due to his authorship of the Psalms |
| Theologus | Augustine of Hippo | 430 |HTML tables allow for elements that span multiple rows or columns, a feature not supported in most Markdown flavors. To compensate for this, any cells that span multiple rows or columns are just repeated to avoid ambiguity. See this table of vowels from the Esperanto Wikipedia page.
<tr>
<th></th>
<th>Front</th>
<th>Back</th>
</tr>
<tr>
<th style="text-align: right;">Close</th>
<td><span style="font-size:125%;">i</span></td>
<td><span style="font-size:125%;">u</span></td>
</tr>
<tr>
<th style="text-align: right;">Mid</th>
<td><span style="font-size:125%;">e</span></td>
<td><span style="font-size:125%;">o</span></td>
</tr>
<tr>
<th style="text-align: right;">Open</th>
<td colspan="2"><span style="font-size:125%; padding-left: 35px;">a</span></td>
</tr>
The a vowel that spans two columns at the bottom would be repeated, and the Markdown would appear as so:
| | | |
|-------|-------|------|
| | Front | Back |
| Close | i | u |
| Mid | e | o |
