Public Sub RemoveColumn( _
   ByVal column As Integer _

public void RemoveColumn( 
   int column
)

Parameters

column: Index of column to remove

Exception	Description
System.ArgumentOutOfRangeException	Specified column is out of range; must be between 0 and total number of columns

This example creates a new DefaultSheetDataModel, sets its number of rows and columns in the constructor and attaches it to the DataModel of the active sheet. Data is added to the first cell in the first three columns. In a button click event the RemoveColumn method removes the first column.
