我认为这是你的问题：

 // returns an array for each row. Since t here is only one row, 
 // there will be only one item in the array.
 var data = table.rows(current_row).data(); 

console.log('Row data:' + data);

var rowData= data[0];
// now you need the column  that it belongs to
$("#ID").val(rowData[0]); // assuming that id is in the first column
