Typing in NumberColumn error

[Hassan Kbbewar]

when you type in number column when the old value is null it works but if you try to edit previous value it takes the first digit and correctly but the caret moves to decimal and when you enter second digit it change the decimal instead of the main digit and it also create exception : Exception in thread "JavaFX Application Thread" java.lang.IllegalArgumentException: The start must be <= the end. and could you make the number column if no decimal digits in the value omits the .00 thanks
