This closes #1462 and closes #1464

- Support creating a conditional format with a "stop if true" rule
- Support set border color and create solid color for the color data bar
- Fix incorrect cell type when modifying string cell with the time number
- Update unit test for the add pivot table to avoid pivot table range overlap
