I am trying to draw table in latex but when I compile my latex file it misses one boarder line of the table as you can see in this image. I have tried all possible way but no luck if any one can help. Here is the image that shows missing boarder line in bottom
and this is my code that i use to generate table
\begin{table}
\begin{adjustbox}{max width=\textwidth}
