Nifi || Mail || Display csv files content in tabular format.

To get it into a table, you need something like this:

<table><tr><td>
${'$1':replace(',','</td><td>'):replace('\n','</td></tr>\n<tr><td>')}
</td></tr></table>

and it should output an HTML Table like this:

<table><tr><td>
Release Cause</td><td>Previous Count</td><td>Current Count</td><td>Change_Ratio</td><td>SEVERITY</td>
</tr><tr><td>SIP: [487] Request Terminated</td><td>173</td><td>393</td><td>1.271676300578034682</td><td>Critical
</td></tr></table>

You may have to play with the last </td></tr> depending on if you have an empty line on bottom or not.

You may also have to adjust \n to \r\n again depending on the source file actual return chars (not seen they are hidden).
