先上效果图：





上图就是打印的效果，但表格的样式没有出来，在vue-cli脚手架里样式是起作用的。

这个打印是用的原生javascript的方法实现的，但引用了vue.js和element
代码如下：

第二种表格



这个是vue-cli脚手架里用的打印功能。

通过npm 安装插件
1，安装  npm install vue-print-nb --save
2，引入  安装好以后在main.js文件中引入
  import Print from 'vue-print-nb'
　Vue.use(Print);  //注册

3，现在就可以使用了


  <div id="printTest" >
    
    　　　　　　<p>锄禾日当午</p>
    
    　　　　　　<p>汗滴禾下土 </p>
    
    　　　　　　<p>谁知盘中餐</p>
    
    　　　　　　<p>粒粒皆辛苦</p>
    
    　　　　</div>
    
    　　　　<button v-print="'#printTest'">打印</button>

现在就把表格代码贴出来：
  <el-dialog title="设备厂内迁移单预览" v-dialogDrag :close-on-click-modal="false" :visible.sync="printDialogVisible" width="99.5%">
            <el-button type="primary" @click="printDialogVisible = false">返回</el-button>
            <el-button type="success" v-print="'#printTest2'"><svg-icon icon-class="print"/>打印</el-button>
    				<div id="printTest2">
    					<table border= "0" width="99.5%">
              <thead>
                       <tr>
                         <th colspan="12">{{daolist.transferInCompanyName}}</th>
                       </tr>
                       <tr>
                          <th colspan="12">设备厂内迁移单</th>
                       </tr>
                       <tr>
                         <td colspan="12"><span>调出单位：{{daolist.transferOutCompanyName}} / {{daolist.transferOutFactoryName}} / {{daolist.transferOutDepartmentName}}</span></td>
                       </tr>

              </table>
    				</div>
    			</el-dialog>

这个是一个弹框里的内容。

css代码：
  #printTest2 table{
      border-collapse:collapse;
    }
    #printTest2 table thead th{
      font-size: 20px;
      padding:10px;
    }
    #printTest2 table tbody tr{
      height:30px;
      font-size:14px;
    }

    #printTest2 table tbody td span{
      margin-right:20px;
    }

第三种表格的写法

这个几种表格的格式是不一样的：
代码：

            <el-button type="primary" @click="printDialogVisible = false">返回</el-button>
            <el-button type="success" v-print="'#printTest1'"><svg-icon icon-class="print"/>打印</el-button>
    				<div id="printTest1">

                       </tr>
                </thead>
                <tbody>

以上，就是我写的关于Winform打印表格 / 输出到Excel打印的操作，以作记录

前言
最近有个需求，是需要用WinForm打印表格，打印机是针式打印机，纸张则为发票联式的纸张（一联大小大概20cm*10cm），本文列举了两个打印方法，一个是用WinForm自带的打印类，另一个则是将表格输出到Excel后再打印。
主页面 Form1.cs[设计] 介绍
首先先来看下页面的主要设计：


RowMergeView ，这里涉及到一个问题，就是表格要求过长字符换行并且有的单元格需要合并，但是如果使用DataGridView合并单元格，则合并了之后系统只是将两个单元格之间的边框变成白色，实际上还是两个单元格，这样换行的字符就无法正常显示，所以用了别人的RowMergeView插件；
Panel嵌套Label和RowMergeView，直接打印Panel。

表格打印设置 From.cs

复现场景：

1.在Excel中针对以下表格已经设置过自动调整行高，且编辑状态下展示正常：

2.在打印预览和打印纸质文件状态下，第五行内容并未显示出来（当前使用的字体为宋体，字号11号）：

3.当前可以达到打印效果正常的方式：将表格中文字字体设置为“等线”，效果如下：

excel是一款非常好用的电子表格软件，我们经常使用它来记录我们生活中工作中的一些信息、一些数据，当我们整理一些数据信息的时候我们需要将其打印出来使用，这应该怎样操作呢？不用担心，一起来学习学习吧！

当然第一步就是需要我们打开excel表格文档，进入到我们需要打印信息表格界面，我在这里用简单数据表格信息进行演示。
如图：
在这里插入图片描述

然后我们在excel上方菜单工具栏当中点击“文件”。
如图：
在这里插入图片描述

点击进入到文件操作窗口界面，在左侧选项中选择“打印”。
如图：
在这里插入图片描述

然后我们就进入到打印的编辑界面了，在打印界面可以选择打印机、设置打印份数、以及打印文档格式、纸张大小、边距等等设置，按照自己所需求的打印方式进行设置。
如图：
在这里插入图片描述

当我们设置好打印的格式，确认完毕好可以打印了，然后我们点击上方的“打印”按钮即可完成打印。
如图：
在这里插入图片描述

完成以上步骤我们就可以把我们表格文档中的内容进行打印出来了，很是简单且方便快捷，希望能够帮助到大家，感谢大家的观看。
