2 standard things:
1) Turn on ALL your table lines, inside and outside and PRUNE.
Looks like you have extra tables inside tables inside tables when I view your site.
You can always hide the lines again (use dotted lines inside/outside).
2) IN CSB, on the TOOLS menu, choose OPTIONS, TEXT tab.
Check the box to show hidden characters, especially SPACES. You will see ...... whereever you have extra spaces. They DO NOT publish! You can leave this on all the time (I do) to keep from having extra spaces that can cause problems!
