One way would be to create a custom stoke style (type Stripe) with a low percentage of the height top and bottom devoted to the stripes, then apply color to the Gap in the dialog whn you apply the stroke style to your paragraph rule. The down-side to this is that the "weight" of the two lines will vary as you change the actual stroke weight.
To avoid that, and still be able to ge the fill to extend to the column width you could use a 1-cell table, or you could use rules above and below, and a cutom underline for the fill, and pad the line with a right-indent tab. If you need space on the left, as indicated in the illustration, you'd probably need a leading tab as well, rather than an indent.

I have a document where I almost do such, but without the fill. I use a Head Style which Spans Columns for this instance; it allows the haeds to flow and fill the width.
Paragraph Rules above and below are turned on with plenty of offset.
I tweaked my setting to accomodate your need - It required only one instance, not above and below, and changing the stroke to a double stroke.
It may be necessary to create a custom stroke to modify the proportion of stroke vs fill. There is a difference of thin-thin and thick-thick, neither of which seemed perfect but might be dependent on the Character height.
Creating custom strokes is accomplished via the Strokes Panel.
