Vue项目中将表格内的数据导出为Excel文件

# Vue项目中将表格内的数据导出为Excel文件
~~~markdown
# 首先安装三个依赖
    npm install -S file-saver xlsx
    npm install -D script-loader

# 引入两个js文件
    在src目录下新建excel文件夹，里面放入Blob.js和Export2Excel.js两个JS文件

https://blog-static.cnblogs.com/files/blogs/680574/Blob.js

 

# 在main.js引入这两个文件(路径取决你们的路径)【也可以不引用】
    import Blob from "@/excel/Blob"
    import Export2Excel from "@/excel/Export2Excel"
~~~

### 正确设置路径

~~~js
# 在Export2Excel.js文件中正确导入Blob.js文件

require(\'script-loader!file-saver\');
// require(\'script-loader!vendor/Blob\');
require(\'@/excel/Blob\');
require(\'script-loader!xlsx/dist/xlsx.core.min\');
~~~

### 调用export2Excel()方法即可导出为excel

~~~js
export2Excel() {
      require.ensure([], () => {
        const { export_json_to_excel } = require(\'@/excel/Export2Excel\');
        // 设置Excel的表格第一行的标题
        const tHeader = [];
        const filterVal = this.singleKeys;
        for (let i = 0; i < filterVal.length; i++) {
          let v = this.singleNames[filterVal[i]];
          tHeader.push(v)
        }

        const list = this.tableData;  //把data里的tableData存到list
        const data = this.formatJson(filterVal, list);
        export_json_to_excel(tHeader, data, \'列表excel\');
      })
    },
    formatJson(filterVal, jsonData) {
      return jsonData.map(v => filterVal.map(j => v[j]))
    },

        var url = window.URL.createObjectURL(blob);
        var aLink = document.createElement("a");
        aLink.style.display = "none";
        aLink.href = url;
        aLink.setAttribute("download", name);
        document.body.appendChild(aLink);
        aLink.click();
        document.body.removeChild(aLink); //下载完成移除元素
        window.URL.revokeObjectURL(url); //释放掉blob对象
      })
    },
