Hello  
I want to traverse columns wise. How can I do that.  
Example  
Empid. Emasalary

1. 

```
     100000

```

2. 

```
     200000

```

3. 

```
     300000

```

Sum of salary = 600000

How can I do this in JavaScript without using groupby

Hi Shubham,

if (getProcessCount(“r”) == 1) {  
var lastCredit = 0;  
}  
lastCredit = lastCredit + credit;

Relace credit with your column name.
