ProgressBar progressBar = new ProgressBar(shell, SWT.NONE);
progressBar.setBounds(398, 10, 210, 21);
progressBar.setMaximum(100);
progressBar.setMinimum(0);

Object[] columnNames = {"姓名", "语文", "数学", "英语", "总分"};
Object[][] rowData = {
{"1", 80, 80, 80, 240},
{"2", 70, 80, 90, 240},
{"3", 70, 70, 70, 210},
{"4", 80, 70, 60, 210},
{"5", 80, 70, 60, 210}
};
table_1 = new Table(rowData,columnNames); 为什么说我这里没定义~~构造函数 Table（Object[][], Object[]）未定义
table_1.setBounds(31, 10, 348, 155);
table_1.setHeaderVisible(true);
table_1.setLinesVisible(true);
}
