borders and table/cells

Hello - I have read through here looking for a resolution. I can’t find one that helps me or works for me. I am having trouble with the borders on tables. whether it’s a border around the whole table only or borders around the cells. I have used in-line css and style sheet css. My results always vary. For example - I get borders on all sides except one side or one side border is thicker than the others. I have printed the pdf’s to verify and it looks like it does in designer. I am using 0.5pt. Does anyone have any ideas as to how I can get consistent results? I can style two tables the exact same way and get two different results.

Thank You

It would look different if one table has the property collapse on and the other off.

Also, when zooming in or out, you could see things that looks different.

Without your Template example, it is hard to troubleshoot.
