how to access html element which doesn't have a wicket:id - wicket

Question

I am new to wicket ,Please someone help me with a thought. I have a logic around a checkbox to display or not to display.
Problem:
when the logic of not to display a checkbox is on , which is by adding a display:none to the checkbox element dynamcially in code , there is a white space because of td surronding the checkbox.
my html looks like
<span wicket:id="checkgroup">
<table>
<tr wicket:id="srow" >
<td><input type="checkbox" wicket:id="scheck"/></td>
<td><img wicket:id="sicon"></img></td>
</tr>
</table>
</span>
so in code I have if else logic for adding a display:none to check box element which removes the checkbox from the view which looks like the below
<span wicket:id="checkgroup">
<table>
<tr wicket:id="srow" >
<td><input type="checkbox" wicket:id="scheck" style="display:none"/></td>
<td><img wicket:id="sicon"></img></td>
</tr>
</table>
</span>
final CheckGroup<Scope> checkGroup = new CheckGroup<>("checkGroup",
new ArrayList<> ());
ListView<Scope> listView = new ListView<Scope>
("srow", sList);
#Override
protected void populateItem(final ListItem<S> item)
{
Check<S> check = new Check<>("scheck", item.getModel(), checkGroup);
if(defaultscope)
{
check.add(new AttributeModifier("style","display:none"));
}
item.add(check);
}
so now my checkbox disappears but the surrounding td stays and causing a white space in display.
Any ideas on how to approach this issue.
Thanks.

You can use <wicket:enclosure> to remove html if the referenced child is not present. wicket enclosure.
Your code in populateItem could look like this:
Check<S> check = new Check<>("scheck", item.getModel(), checkGroup);
if(defaultscope)
{
check.setVisible(false);
}
item.add(check);
Your markup would look like this:
<tr wicket:id="srow" >
<wicket:enclosure>
<td><input type="checkbox" wicket:id="scheck"/></td>
</wicket:enclosure>
<td><img wicket:id="sicon"></img></td>
</tr>
