The ColumnStyle class represents the user interface (UI) characteristics of column in a TableLayoutPanel. The styles for all the columns in such a table are collected in the TableLayoutPanel.ColumnStyles property.

This simple class offers the Width and SizeType properties for a column.

The following code example demonstrates how to extract a ColumnStyle from a TableLayoutColumnStyleCollection.

This code example is part of a larger example provided for the TableLayoutPanel class.

private void toggleColumnStylesBtn_Click(
    System.Object sender, 
    System.EventArgs e)
    TableLayoutColumnStyleCollection styles = 

    foreach( ColumnStyle style in styles )
        if( style.SizeType == SizeType.Absolute )
            style.SizeType = SizeType.AutoSize;
        else if( style.SizeType == SizeType.AutoSize )
            style.SizeType = SizeType.Percent;

            // Set the column width to be a percentage
            // of the TableLayoutPanel control's width.
            style.Width = 33;
            // Set the column width to 50 pixels.
            style.SizeType = SizeType.Absolute;
            style.Width = 50;
