> Problem:
> In a text element containing a table a single "0" in a cell isn't rendered
> properly in the FE outbut but a "1" (for example) does:
>
>  <td>0<td> becomes to <td>&nbsp;</td> but
>  <td>0&nbsp;</td> stays <td>0&nbsp;</td> and
>  <td>1</td> stays <td>1</td>
>
>
> Solution:
> Introduce new stdWrap property "ifBlank" and modify the table rendering TS
> accordingly.
>
> Background information:
> The "ifEmpty" stdWrap is unfortunately not doing what it claims to be: It
> doesn't check if a string is empty, instead it just tests if the value is
> true or not. (Therefore the TSref contains a notice that "Zero's are an
> empty value!")
>
> The solution is to add a new property which compares the value using
> strcmp('',$value).
>
>
> Documentation:
> ifBlank
> string / stdWrap
> Same as "ifEmpty" but the check is done using a binary comparison (strcmp).
