# Table with different column width

I am preparing to send my article to a Springer journal for the first time. I want to insert a two column Table as shown in the following image:

while my code produces:

• @ christian Hupf, if you run the code you will see that my table is not like in the image, How can I fix this problem. Apr 16 '17 at 13:36

Not sure which features you want to change:

• If you want the middle column to be broader, use X and it will fill all the available space.
• If you want to align the numbers in the right columns, use for example siunitx.
• For the spacing around the top line, booktabs might help.
• @{} removes the protruding lines
