I have gotten this to work in a drawing where the styles all reside in the same drawing.
However, have any of you tried setting this up in a reference template and then using this setup in another drawing with the template referenced in to it? The property sets and styles come through and the label styles work fine, but the table style, while being coded correctly, will not show the correct data until I edit the table style, in which case I select the option to use the revised table in the current cad session only. Then the table populates the data with the property set information. When I close and re-open the drawing though, the table data goes away, only showing question marks. The table style looks correct though. Using Civil 3D 2021.
