I have this weird thing with wiki syntax: Consider a template with
"optional columns", like so:
{|
! Foo
{{#if: {{{bar|}}} | ! Bar}}
{{#if: {{{baz|}}} | ! Baz}}
|-
| {{{foo}}}
{{#if: {{{bar|}}} | {{!}} {{{bar}}}}}
{{#if: {{{baz|}}} | {{!}} {{{baz}}}}}
|}
Now, if I transclude that template and leave out {{{bar}}} and
{{{baz}}}, I get this markup:
<table>
<tr>
<th> Foo
<p><br />
</p>
</th></tr>
<tr>
<td> {{{foo}}}
<p><br />
</p>
</td></tr></table>
This is clearly, then, caused by the newline between the canditional
bar and conditional baz lines resolving to empty strings, making the
foo cells in each row have paragraphs containing line breaks. So how
do I get rid of it without, say, putting both rows into one compact row?
