这里面包含了一百多个JAVA源文件

The following creates a table that uses an efficient underlying storage implementation. Although cell values can be changed, rows and columns cannot be added or deleted. 
    // Create with initial data
    Object[][] cellData = {
        {"row1-col1", "row1-col2"},
        {"row2-col1", "row2-col2"}};
    String[] columnNames = {"col1", "col2"};
    
    JTable table = new JTable(cellData, columnNames);

The following creates tables that allow rows and columns to be added or deleted: 
    // Create a table with empty cells
    int rows = 10;
    int cols = 5;
    table = new JTable(rows, cols);
    
    // Create a table with initial data
    Vector rowData = new Vector();
    for (int i=0; i<cellData.length; i++) {
        Vector colData = new Vector(Arrays.asList(cellData[i]));
        rowData.add(colData);
    }
    Vector columnNamesV = new Vector(Arrays.asList(columnNames));
    
    table = new JTable(rowData, columnNamesV);
