# Indicate that the 1st line contains column names.

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

# 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.
$weightColumn = $csv.GetIndex("Weight")
$("Weight Column Index = " + $weightColumn)
$csv.InsertColumn($weightColumn)

$($csv.SaveToString())

# We now have:

#  101;Lisa;Denver;;120

# Set the cells in the new column:

$csv.SetColumnName($weightColumn,"Height")
$csv.SetCell(0,$weightColumn,"6' 2`"")
$csv.SetCell(1,$weightColumn,"5' 7`"")
