I wish the content in the Datatemple would be filled in the proportion I set but in fact they are very close together. This problem annoys me very much and I would love to get your answer

I try to set up HorizontalContentAlignment = “Stretch” the result is close together

This is what I would expect:

This style uses a fixed width, I want the style to be proportional to the swing
