How to: Manipulate a Table's Columns through the Columns Property

This example demonstrates some of the more common operations that can be performed on a table's columns through the Columns property.

The following example creates a new table and then uses the Add method to add columns to the table's Columns collection.

Table tbl = new Table();
int columnsToAdd = 4;
for (int x = 0; x < columnsToAdd; x++)
    tbl.Columns.Add(new TableColumn());

The following example inserts a new TableColumn. The new column is inserted at index position 0, making it the new first column in the table.


The TableColumnCollection collection uses standard zero-based indexing.

tbl.Columns.Insert(0, new TableColumn());

The following example accesses some arbitrary properties on columns in the TableColumnCollection collection, referring to particular columns by index.

tbl.Columns[0].Width = new GridLength(20);
tbl.Columns[1].Background = Brushes.AliceBlue;
tbl.Columns[2].Width = new GridLength(20);
tbl.Columns[3].Background = Brushes.AliceBlue;

The following example gets the number of columns currently hosted by the table.

int columns = tbl.Columns.Count;

The following example removes a particular column by reference.


The following example removes a particular column by index.


The following example removes all columns from the table's columns collection.
