Hi all!

I am generating HTML with a lot of table content, that is in the <td>
tags. With my table cells, I always get empty cells with *no borders*
when <cut> ing the empty string (in Java: String str = ""

Is there any way get <td> cells *with borders* when <cut> ing the
empty string?

I think this is a browser issue, IE right?
<td></td> produces borderless cells in IE
fix is
<td>&nbsp;</td>
not sure when or if this has been fixed.

Try netscape to confirm.

Could be. I have almost no HTML/browser experience.

Nope. Netscape 7.1.

Hmmm. This insert a socalled non-breaking space to every cell...

I mostly pass String objects to JSTL. How can I query on a String object
from JSTL, whether it's the empty "" string? Like this, only &nsbp; will
be output if the string is empty ("").

The bad thing is, to use it for every cell, the text will shift to the
right one space, which looks uglier than before.

Any recommendations here?

Just write a <c:if> tag that checks wether the String was emtpy/null and
writes a &nbsp; if that was the case.

I t might also be possible to force borders on your tablecells using css, so
you might want to check that in some html/css newsgroup.

How exactly does a JSTL if look like, that can check for the empty string???

Not quite... you probably meant something like:

<c:choose>
<c:when test="${empty cell.contents}">
&nbsp;
</c:when>
<ctherwise>
<cut value="${cell.contents}"/>
</ctherwise>
</c:choose>

Is this seriously what you do in JSTL? In BRL I do

[(or (brl-nonblank? my-string) "&nbsp;")]

It could be written a tad shorter.

<cut value="${cell.contents}"/>
<c:if test="${empty cell.contents}">
&nbsp;
</c:if>

In JSP 2 you can just write:

${cell.contents}
<c:if test="${empty cell.contents}">
&nbsp;
</c:if>

You could also make a custom tag like this:

<t:addSpaceIfEmpty value="${cell.contents}"/>

If the non-breaking space in those table cells makes your tables look
ugly, what about:

<cut value="${data}" default="&nbsp;" />

Doesn't the default signify what to put in case there is no value?
