Column

Remark

The Column class provides methods and properties common to Origin worksheet columns. An Origin C Worksheet object has a collection of Column objects each of which in turn holds a Dataset. A Column object is primarily used for style related control of the data in the associated Dataset.

An Origin C Column object is a wrapper object that is a reference to an internal Origin column object. Wrapper objects do not actually exist in Origin and merely refer to the internal Origin object. Consequently, multiple Origin C wrapper objects can refer to the same internal Origin object.

The Column class is derived from the DataObject, DataObjectBase, and OriginObject classes from which it inherits methods and properties.

void Column_Ex1()
{
    Worksheet wks = Project.ActiveLayer();
    if(!wks)
        return;
    int ii = 1;
    foreach(Column cc in wks.Columns)
    {
        string strLabel;
        if(cc.GetLabel(strLabel) > 0)
            printf("Column(%d) has label = %s\n",ii++, strLabel);
    }
}
