Jtable 删除行问题

Question

我想删除表所有行，执行有错误；int rows = Authortable.getRowCount();
   
for(int j=0;j<rows;j++)
{
 DefaultTableModel tableModel = (DefaultTableModel) Authortable.getModel();
 
tableModel.removeRow(j);// rowIndex是要删除的行序号 }
报错如下：

Answer 1

楼主这样试试：
DefaultTableModel tableModel = (DefaultTableModel) Authortable.getModel();       
for(int j=0;j<tableModel.getRowCount();j++)
{
   tableModel.removeRow(j);// rowIndex是要删除的行序号}

Answer 2

肯定不能这样用的，你已经removeRow了，tableModel的实际行数就少了，这肯定就报数组越界错误！LZ直接清空tableModel算了，应该有这个方法，具体忘记了，不好意思

Answer 3

 ((DefaultTableModel)table.getModel()).getDataVector().removeAllElements();
