The table is copied with an extra straight line

In CAD, I copy the table with two separate commands, but the copied table with ctrl+c has a line。thanks all.

Its not so much that there is an extra line there, but your table formatting is a bit weird. 
If you have a look at the data type of each of those rows, they're all "headers". the row heights vary abit which indicates something changed etc. 

I took your file and ran our company based remove-formatting routine on it and my tables come out looking as per the attached file. Suggest revisiting your table style?

The cell height of the third row of this table wants to be set to a relatively small size. And the top three rows are set to not show borders。I am on your file, after resetting, the bottom border of that line is still displayed after copying。 thanks .

Hello @cadhome 

There seems to be like the border color of the table has been edited. On my end, even when I use the command "COPY" or use "ctrl+C" the result is the same and I am seeing an additional line in the table. Are you looking for color differentiation in the table? If not, use the command "SETBYLAYER" on the table,  to set the color of the table border to be bylayer to follow the layer color set to the table.
