InDesign Table Grid Lines Disappear when Exported to PDF
Hi,
I am currently using InDesign to create a document, and I have created a certain table in this document. This table has several rows and columns, and in some cells there are text and in other cells there are images directly inserted into the cell. My problem is that for no apparent reason some of the grid lines between the cells completely disappear or become invisible when I export to PDF. Furthermore, these specific lines become thinner when I zoom out in InDesign, but other lines do not. Does anyone have a solution to this?

Thanks.
