Table borders offset in PDF output
I am using RoboHelp HTML, version 9 and I need to deliver two outputs for my documentation: WebHelp and PDF.
My table borders look the way I want them to in WebHelp and Word, single line and thin (1px).
But when we go to PDF, I get two sets of lines, one all the way around my cells, another with gaps of white space.
I think its something to do with 3d borders not getting totally eliminated.
I've added "table-collapse: collapse;" to all my table styles.
Any ideas?
Note: If I create a table originally in Word with thin single line borders, it looks fine in PDF.
Here's how it looks in WebHelp and Word...

And then in PDF...
