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.
