Java jTable计算每行

DefaultTableModel model = (DefaultTableModel) jTable.getModel();
int rowCount = model.getRowCount();
int columnCount = model.getColumnCount();

for (int row = 0; row < rowCount; row++) {
    // 获取每行的数据
    Object[] rowData = new Object[columnCount];
    for (int column = 0; column < columnCount; column++) {
        rowData[column] = model.getValueAt(row, column);
    }

    // 计算每行的值
    // 假设需要计算第1列和第2列的和，并更新到第3列
    int sum = (int) rowData[0] + (int) rowData[1];
    rowData[2] = sum;

    // 更新表格数据
    model.setValueAt(sum, row, 2);
}
