1. Regarding the cell background color, can you please ensure that the Zoom% in PDF is 100. Because background is exported as command, when the Zoom is not 100%, they may not match and the issue also depend on PDF Viewer. With the specified zoom, the issue may be seen in a PDF Viewer but not other PDF Viewer.
So, to please try to set viewer zoom to 100%. This has resolved the problem for me.
2. Regarding the cell border extending: This is a bug in control and will be fixed in a future release version [ID:12015]. I will get back to you as soon as there is an ETA available.
