Using Column Value in CSS Style for Column in Report

Question

I am trying to apply a CSS style (background color) to a column in a report based on another column.
So for the Column attributes for a specific column, I would like to be able to add this to the 'CSS Style' Field under the group, "Column Formatting":
background-color:#BKG_COLOR#;
It doesn't seem to be taking my column value, which is #daf2ea
In the CSS Style Field, if I change it to: background-color:#daf2ea - then it works.
So it doesn't seem to take my column value of #BKG_COLOR" in the CSS Style field.
Any ideas? Do I need to use the 'HTML Expression' field instead, and how would I do that?
Thanks,
John

Hi,
that's correct, custom report templates will do.
I find them sometimes quite limited, though. And I always ask myself "how would I do it without APEX", because there's often a lean jQuery solution that affords less coding.
If you employ a so called "marker class" that depends on your colour value, you could begin like in the previous answer and enter the follwing into HTML Expression:
<span class="#BKG_CLASS#">#THE_COLUMN_I_WANT_TO_SHOW#</span>
That means you would not query a plain color, but some name that can act as a CSS marker, like
select THE_COLUMN_I_WANT_TO_SHOW
      , case when THE_COLUMN_I_WANT_TO_SHOW > 100 then 'hotColor' else 'coldColor' end as BKG_CLASS
  from my_tableIn the page's Function and Global Variable Declaration, you'd enter
function colorMyReport () {
  apex.jQuery('.hotColor').closest('td').css('background-color','#FAA');
}And under Execute when Page Loads, you enter:
colorMyReport();There's only one challenge, of course, when the report is paged via AJAX, because the script would only run once (on the first page shown).
But if this is a solution for you, I'd be pleased to show you how to overcome this. Just let me know.
Hope there is no typo in my typing, because I have to catch my train now :-)
Bye!
