QuarkXPress now adds a capability to apply a rule (a line) between two or more columns.
So, you can simply select “Line Between” attribute to draw a line between two columns.
How it works:
a. Go to Text Box tab on Measurement palette and when you have applied 2 or more
columns, you will see option enabled to apply Line Between.
b. You can select Line type, width, color and opacity on the measurement palette.
