fixed cursor jumps issue when removing some text

[RajeshKoram18]

Scenario:

Step1: create 3 * 3 table Step2: click on Row 3 Col1, don't do anything Step3: click on Row 2 Col1, then click backspace. Issue1: Without removing/clearing the Row2 Col1 content, cursor moves to Row2 Col3.

Fix: Prevented the cursor to move other cells instead of focusing the current cell.

Please let me know if you are having any concerns on this.
