you could create a html table out of your tableview data. HTML tables are quite easy to create with some NSString magic.
A very basic table looks like this:

<table border="1">
  <tr>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
  </tr>
  <tr>
    <td>row 2, cell 1</td>
    <td>row 2, cell 2</td>
  </tr>
</table>

the code to create such a table could look like this:

    NSString *tableStart = @"<table border=\"1\">\n";
    NSString *rowStart = @"  <tr>\n";
    NSString *cellStart = @"    <td>";
    NSString *cellEnd = @"</td>\n";
    NSString *rowEnd = @"  </tr>\n";
    NSString *tableEnd = @"</table>";

    NSMutableString *table = [NSMutableString string];
    [table appendString:tableStart];
    for (MyObject *object in self.dataSource) {
        [table appendString:rowStart];  // one row for each object

        [table appendString:cellStart]; // first cell for title
        [table appendString:object.title];
        [table appendString:cellEnd];

        [table appendString:cellStart]; // second cell for rating
        [table appendFormat:@"Rating %d", object.rating];
        [table appendString:cellEnd];

        [table appendString:rowEnd];
    }
    [table appendString:tableEnd];

this will create a very basic table. With some html knowledge you can add more fanciness.

When you have that table embed it in a html document and send the email as html.

If you want to go this way you have to learn the basics of html. There is a lot of information about this in the web. You could start with those two links.
