I can't find a good way to do this in templetor:

I want to check a variable and then show or hide a block of html
depending on its value:

I can use:

$if lots > 0:
    <tr><td align="right">Vessel</td></tr>
$if lots > 0:
    <tr><td align="right">Quantity</td></tr>
....


And also I can check it inside the python code and then render
different templates, but this will complicate the maintenance in some
cases.

I wish I could do something like this:

$if lots > 0:
    <tr><td align="right">Vessel</td></tr>
    <tr><td align="right">Quantity</td></tr>
    ...........................
    <tr><td align="right">Arrive</td></tr>
$endif
