Can I add double bottom border in the Row styling rule?

[Purpose]

I hope below is a simple question related to CSS style syntax. 

I am trying to insert Double line if a certain condition is met.  See below capture for the Row Styling Rules from the table tool.     

"border-bottom-style: solid;" expression does generate a single line.  

"border-bottom-style: double;" expression, however, does add any line to the bottom border. 

The output is to an Excel file.  

Purpose.

On the reporting pallete, on the table tool you will see in Edit Row Rules the same configuration:

afv2688,

Thanks for taking a look at the issue.  I am using the formula checkbox from the bottom of your 2nd screen shot to insert the double bottom line.  

The issue is that below formula is not adding the double bottom line to a row that contains the word Subtotal.  

                     "border-bottom-style: double;"  It simply does not add any line to the row.  

I have updated the screen capture, which provides more detail on the issue.     

Purpose.

Tried it too.

Checked the table configuration tool and as it says on the page:

https://help.alteryx.com/2018.3/PortfolioComposerTable.htm

" Borders: Select to have borders on the left or right sides, or both sides, or to not have any borders. "

So it seems there is no option to put a bottom border (maybe I'm wrong)

I was trying to do something similar in PDF document output -- was not able to get a double underline, but did get a thicker line by using "Border-bottom: 3px solid black;" - not sure if this is something added recently, but visually accomplishes the same thing I was trying to do with the double underline.

Hopefully this helps if someone looks this up someday.

It did help. Thank you!
