</add>This writes 1000 rows of bogus data to output.html.
The template template.vtl is passed a VelocityModel. The template in this example looks like this:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>Velocity Output</title>
</head>
<body>
<table>
<thead>
<tr>
#foreach($field in $Model.Entity.Fields)
#if(!$field.System)<th>$field.Label</th> #end
#end
</tr>
</thead>
<tbody>
#foreach($row in $Model.Rows)
<tr>
#foreach($field in $Model.Entity.Fields)
#if(!$field.System)<td>$row.get_Item($field)</td> #end
#end
</tr>
#set( $Model.Entity.Inserts = $Model.Entity.Inserts + 1 )
#end
</tbody>
</table>
</body>
</html>The table in output.html looks like this (clipped for brevity):
| Identity | FirstName | LastName | Stars | Reviewers |
|---|---|---|---|---|
| 1 | Justin | Konopelski | 3 | 153 |
| 2 | Eula | Schinner | 2 | 41 |
| 3 | Tanya | Shanahan | 4 | 412 |
| 4 | Emilio | Hand | 4 | 469 |
