Returns the number of columns in the column model.

Usage

From source file:Main.java

public TableColumn[] getColumnsInView(JTable table) {
    TableColumn[] result = new TableColumn[table.getColumnCount()];

    // Use an enumeration
    Enumeration e = table.getColumnModel().getColumns();
    for (int i = 0; e.hasMoreElements(); i++) {
        result[i] = (TableColumn) e.nextElement();
    }/*w  w  w.j ava2  s  . co  m*/

    return result;
}
