Add number input type without confirmation and check if table is empty and proceed if it has rows

[vinothvkr]

added number input type without confirmation also aligned the "number-confirm" case.

var currentColumnIndex = table.cell(this).index().column;
.column throws error if the table has no data.

so added check to verify if the table has row with data and proceed.
