The CorelDRAW 2019 users guide gives the following instructions:
To modify cell border spacing in tables
1 Click the Table tool, and then click the table.
2 Click Options on the property bar.
Problem: There is no "Options" on the property bar.
Has anyone been able to adjust cell border spacing in tables?
I discovered the answer to my question. Rather than selecting the table with the table tool, you must select it with the Pick tool in order to get the Property Bar that offers the Options choice with the Separated Cell Borders check box.
