Java Tutorial » SWT » TableColumn

17. 51. 1. Adding Columns

The TableColumn class represents a column in the table. You create a column with a parent table, a style, and optionally an index. If you don't specify an index, the column assumes the next available zero-based index.


public TableColumn(Table parent, int style)

public TableColumn(Table parent, int style, int index)

The supported styles all specify the alignment for the column's contents:

SWT.LEFT for left alignment,
SWT.CENTER for center alignment, and
SWT.RIGHT for right alignment.

You should specify only one of these;
You can change alignment after construction using the setAlignment() method.
Alignment defaults to left and affects all rows in the column.
