func chilkatTest() {
    let csv = CkoCsv()

    // Load the following CSV:

    //  Name;City;Weight
    //  John;Chicago;180
    //  Lisa;Denver;120

    // Indicate that the 1st line contains column names.
    csv.HasColumnNames = true
    var success: Bool = csv.LoadFile("qa_data/csv/insertColumnTest.csv")

    // We can insert a column before the 1st column.
    csv.InsertColumn(0)

    print("\(csv.SaveToString())")

    // The CSV now looks like this:

    //  ;Name;City;Weight
    //  ;John;Chicago;180
    //  ;Lisa;Denver;120

    // Set the cells in column 0.

    var col: Int = 0
    csv.SetColumnName(col, columnName: "id")
    csv.SetCell(0, col: col, content: "100")
    csv.SetCell(1, col: col, content: "101")

    print("\(csv.SaveToString())")

    // We now have:

    //  id;Name;City;Weight
    //  100;John;Chicago;180
    //  101;Lisa;Denver;120

    // Insert a new column between City and Weight
    // In other words, add a new column before the Weight column.
    var weightColumn: Int = csv.GetIndex("Weight").intValue
    print("Weight Column Index = \(weightColumn)")
    csv.InsertColumn(weightColumn)

    print("\(csv.SaveToString())")

    // We now have:

    //  id;Name;City;;Weight
    //  100;John;Chicago;;180
    //  101;Lisa;Denver;;120

    // Set the cells in the new column:

    csv.SetColumnName(weightColumn, columnName: "Height")
    csv.SetCell(0, col: weightColumn, content: "6' 2\"")
    csv.SetCell(1, col: weightColumn, content: "5' 7\"")

    print("\(csv.SaveToString())")

    // We now have:

    //  id;Name;City;Height;Weight
    //  100;John;Chicago;"6' 2""";180
    //  101;Lisa;Denver;"5' 7""";120
