how to convert HTML table to adoc format in adoc

I converted JSON to adoc successful with using Swagger2Markup.

but result was not the thing that I intended for.

|===
|HTTP Code|Description|Schema
|**200**|● Response<br/><table border=1><tr><td width='20%'>code</td>
...

I want to convert HTML Tags in value of JSON to adoc, also.

is there any solution about it?
