will be helpful for those in need So this is a DataTable and you want to skip the first column and take every third column:
code :
List<DataColumn> myColumns = table.Columns.Cast<DataColumn>()
    .Skip(1)
    .Select((col, index) => new { col, index})
    .GroupBy(x => x.index / 3)
    .Select(xg => xg.Select(x => x.col).First())
    .ToList();
foreach (DataRow row in table.Rows)
        Console.WriteLine("Every third field after the second: "
            + string.Join(",", myColumns.Select(c => row[c])));

How to skip a field and only unmarshal a specific member of that field using JAXB?

How to skip a field and only unmarshal a specific member of that field using JAXB?

around this issue To make this specific mapping, add a name getter and annotate it with @XmlElement.
The idea is using name getter and setter defined in Container to allow JAXB rely on the Person field as it marshals or unmarshals the root element.
code :
@XmlElement
public void setName(String name) {
    if (person == null){
       person = new Person();
    }
    person.setName(name);
}
@XmlElement
public String getName() {
     return person.getName();
}

public void setName(String name) {
    if (person == null){
       person = new Person();
    }
    person.setName(name);
}

Hope this helps You can calculate the sum of the quantity of the of each product sold by using a combination of sumif, index/match and offset.
code :
=INDEX($D:$D,MATCH($H$2,$D:$D,0),1)
=OFFSET(INDEX(D:D,MATCH($H$2,D:D,0),1),1,-1)
=INDEX($D:$D,MATCH($H$3,$D:$D,0),1)
=OFFSET(INDEX($D:$D,MATCH($H$3,$D:$D,0),1),1,-1)
=SUMIF($D:$D,$H2,OFFSET(INDEX($D:$D,MATCH($H$2,$D:$D,0),1),0,-1):OFFSET(INDEX($D:$D,MATCH($H$3,$D:$D,0),1),0,-1))
