以下是我尝试对 Jtable 执行少量添加列和添加行时遇到的异常。

哪位大神帮忙看看！！

        for(int i=0;i<local.length;i++){
            //
            String funcVar = local[i][local[i].length-1];

            // fill the sort variables along with the function column
            for(int k=0;k<processInputInfo.getAsciiInitEstimates().getFuncArray().get(funcVar).size();k++){

                String[] rowData = new String[local[0].length + 4];
                for(int j=0;j<local[0].length;j++){
                    rowData[j] = local[i][j]; 
                }

                // fill the parameter name
                if(index == (al.size())){

                ((DefaultTableModel)AsciiInitialEstGui.createAsciiinitGuiInst().asciiIntEstTable.getModel()).addRow(rowData);

            }

        }

将您的代码放在下面的模板中：

SwingUtilities.invokeLater(new Runnable()
{
    public void run(){
        // your code here
    }
});
