According to the above links, i should can select multi cells , but there is 2 problems in your example
1- In case that user select only one single cell , the user can't read its index in console
2- In case that user selected 2 cells , the last cell index will never appears in console until the user select anther cell. so the user must select 3 cells to read 2 cells index !!
3- I faced the same 2 issues (No. 1 & 2) while i am trying to show selected cells after click in a button. please review my example;e http://jsfiddle.net/ttdrv4Ln/13/
