       在Qt中实现对word的操作有两种方式，即QAxWidget的书签标号法和html语言直接读写法，前一种方法自己试用了，感觉不怎么好用，总会出现这样那样的问题，后一种方法则比较易于理解，而且免去了人工定义书签的方法，同时在实现批量报告的过程中可以节省很大的工作量提高工作效率。

       html语言直接读写法：

       这里直接上程序，下面例子中会在word中写入五个表，一幅图（图也是写在表中），根据word模板来写表是一个细活，这个word文件花了一天半才写好，还是前期对html语言不熟，但这也是一个不断学习的过程，喜欢这种感觉，可以不断的学习新东西，每天都在进步着。

       注意：Qt 向word写入中文汉字时，需要对中文字符串做处理: QString::fromLocal8Bit("汉字");

 程序如下：

#include "widget.h"

#include <QApplication>

#include <QAxObject>

#include <QAxWidget>

#include <QDebug>

#include <QAxSelect>

#include <QDir>

#include <QTextCodec>

#include <QString>

#include <QDateTime>

QString GeneratePicWord()

{

    QString html;

    //文字部分

    QDateTime current_date_time = QDateTime::currentDateTime();

    QString current_date = current_date_time.toString("yyyy-MM-dd hh:mm:ss ddd");

    QString s_paper_name = QString::fromLocal8Bit( "报告" );

    QString s_paper_title = QString::fromLocal8Bit( "***********" );

    QString imagepath = "f:/115.jpeg";

    long showHeight = 100;

    html += "<h2 align=\"center\">" + s_paper_name + "</h2>";

    html += "<h4 align=\"center\">" + s_paper_title + "</h2><br>";

//    html += "<img align=\"middle\" src = \"" + imagepath + "\"  width=\"100\" height=\""+QString::number(showHeight) + "\"/><br>" ;

    html += "<table align=\"center\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\" width=\"645\" >";

    html += "<tr>";

    QString fieldname;

    QStringList fields;

    fields <<  QString::fromLocal8Bit( "*****" ) <<  QString::fromLocal8Bit( "*************" )

    html +="<td align=\"center\" width=102 height=20 colspan=\"1\">" + fields.at( 0 ) + "</td>";
