QTableWidget&QTableView表格美化

本文主要是一个表格的Demo （间隔变色的功能）。涉及到QTableview 和QtableWidget的一些功能。写的不好仅供参考：
图的样式如下：

头文件 .h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    void  initTable();
private:
    Ui::MainWindow *ui;

};
#endif // MAINWINDOW_H
