Can table and cell styles automatically achieve this effect?
The first line is the header, can you use the table style and cell style to automatically realize that the left and right lines are empty and the top and bottom lines are bold?
The first one in the figure below is implemented automatically, and the left and right headers are not empty (this is not what I want).
The second is the effect I want, which is to manually set the left and right lines of the meter head to 0 on the basis of the first one.
------
Note: The first line must be the header
