How can I put some white space between consecutive bigdelim braces in tabular, without inserting space between rows?

How can I put some white space between consecutive bigdelim braces in
tabular, without inserting space between rows?

In one column of a table (using the tabular environment), I have
consecutive braces created using the bigdelim package, as in the
following:
&\rdelim\}{3}{60pt}[\ S--S--L]
&
&
&\rdelim\}{2}{60pt}[\ L--L]
&
I dislike that the tips of these braces touch, and I want to introduce
some white space, but I do not want to introduce extra space between any
of the rows.
I tried using a non-integer value (e.g. \rdelim}{2.8} etc.) but evidently
that doesn't work. Having read the multirow documentation, I thought it
might. I am using MikTeX and apparently my version of multirow was
packaged in May 2004.
If there is an easy solution to this, I would love to hear it. I don't
particularly want a complicated workaround. Thanks!
