Images Not Centered

I have a table and in the first cell I have an image in it. I centered the image in the editor but when I view the page, the image is not centered. I’ve tried it with or without being in a table but it is still not centering. I am also having the same issue with links and other text. What am I missing here?

Here is the code for the image:
<img class="size-full wp-image-179 aligncenter" src="https://mysite.com/wp-content/uploads/2016/09/FLVPK.jpg" alt="VPK" width="168" height="160" />

Thanks,
Greg
