Changes

in your note's frontmatter

I confused the "property" from Dataview ([key:: value]) with the note's frontmatter properties. My bad.

table.dataview

table is the name of the HTML element, dataview is the name of the class. Not the other way around.

dv.container.classList.add('clsname')

It's better practice to edit the classes of an element through the classList property than by appending strings to the className property.
