Table Sorter for String displaying Numbers

Question

Hi All.
I have a table whose one of the columns display numbers with data type string. This is becuase :
1. RFC gives me as String.
2. I have to display blank in case no value or zero is present (since int, long etc default to Zero, hence  
    not used).
I have to sort this column as a number.Since the datatype is string, it sorts the numbers as string
for example : if we have  values like : 2, 4, 3, 10, 19, 15, 20, 22
currently as String it sorts as follows : 10, 15, 19, 2, 20, 22, 3, 4.
but i want as follows : 2, 3, 4, 10, 15, 19, 20, 22.
Useful answers will appreciated.
Thanks and regards,
Aditya Deshpande.

In order to sort the node with attribute of type string; please use the following code..
Here use the node where you store the string value..
wdContext.nodeTest().sortElements(
            new Comparator() {
               public int compare(Object o1, Object o2) {
                    // TODO Auto-generated method stub
               IPrivateExperimentView.ITestElement ele1 = (IPrivateExperimentView.ITestElement)o1;
               IPrivateExperimentView.ITestElement ele2 = (IPrivateExperimentView.ITestElement)o2;
                    return Integer.parseInt( ele1.getNumStr()) > Integer.parseInt( ele2.getNumStr()) ? 1 : -1;
input :  "2", "4", "3", "10", "19", "15", "20", "22"
result : "2", "3", "4", "10", "15", "19", "20", "22"
