HT2506 Trouble with Annotating by Column

Question

I'm trying to annotate (highlight) a column of text that's in a grid in a PDF file. I can select the column using the option button, but when I choose to "highlight" it, it reverts to text that's highlighted by whole lines (NOT a column). It took me a while to learn about using the option button to be able to SELECT a column of text, so maybe this just involves another "trick" I haven't learned yet.
I'm assuming that I should be able to annotate whatever I have highlighted. If this is correct, how do I do this?

Answer 1

You can try something like this example:
SQL> select decode(gr,1,dname,null) dname, ename, job
  2  from (
  3  select count(1), d.dname,e.ename,e.job, grouping(e.ename) gr
  4  from dept d, emp e
  5  where d.deptno = e.deptno
  6  group by grouping sets (d.dname, (d.dname, e.ename, e.job))
  7  order by d.dname,gr desc
  8  )
  9  /
DNAME          ENAME      JOB
