Setting the background of a cell in a table using the rest API

[rc]

I'm currently trying to set the background of a specific cell to red, but am generating:
No JSON object could be decoded

The request I send in is:

{"type":"page","title": "Comparison","ancestors":[{"id":122755880}], "space":{"key":"aaaa"},"body":{"storage":{"value": "<h1>Categories</h1><h2>Miscellaneous Categories</h2><table><tr><td><strong>Category</strong></td><td><strong>Duration (MM:SS)</strong></td><td><strong>Duration (MM:SS)</strong></td></tr><tr><td>File System Creation</td><td>0:52 </td><td class="highlight-red" data-highlight-colour="red" title="Background colour : Red"> 0:26</td></tr></table>", "representation":"storage"}}}

To me it looks like you have not escaped out the quote marks in the page content. You need to escape those out or the first quote mark it comes across it will believe ends the opening one for the storage value, which will make the rest of the stuff you have invalid JSON.
