关于vue.js:用element开发一个复杂表格

jiezi

先上原型图，用 element 制作一个相似这样的表格，刚开始想的是用一个表格去实现，然而 … 想多了，最初用多个表格沉积实现，（注：只关注表格实现，表格中所有数据都是捏造的。）

1、客户根本信息表格

此表格次要做以下操作，1、删除生成表格的第一行空表格（为什么会有空行，还没明确，有晓得的搭档能够留言告知），2、合并客户名称值的列，3、将客户名称值字段靠左显示 

<el-table
    :data="tableData"
    size="mini"
    class="mt10 tableBaseInfo"
    :header-row-class-name="hiddenHeaderRow"
    :span-method="arraySpanMethod1"
    :cell-class-name="setTextLeft"
  >
    <el-table-column label="客户根本信息" align="center">
      <el-table-column prop="name" align="center"></el-table-column>
      <el-table-column prop="nameValue" align="center"></el-table-column>
      <el-table-column prop="month" align="center"></el-table-column>
      <el-table-column prop="monthValue" align="center"></el-table-column>
    </el-table-column>
  </el-table>

    export default {data() {
            return {
                tableData: [
                  {
                    name: "客户名称",
                    nameValue: "测试 1",
                    month: "",
                    monthValue: "",
                  },
                  {
                    name: "客户户号",
                    nameValue: "123456789",
                    month: "结算月份",
                    monthValue: "2",
                  },
                ],
            }
        },
        methods: {
            // 暗藏表格空的行 -- 这块的起因还没搞清楚，生成的表格会有一行是空的
            hiddenHeaderRow({rowIndex}) {if (rowIndex == 1) {
                // 暗藏第二行
                return "hiddenClass";
              }
            },
            // 合并客户根本信息表格客户名称单元格
            arraySpanMethod1({rowIndex, columnIndex}) {if (rowIndex == 0) {if (columnIndex != 0) {return [1, 3];
                }
              }
            },
            // 设置客户根本信息表格客户名称靠左显示
            setTextLeft({rowIndex, columnIndex}) {if (rowIndex == 0) {if (columnIndex != 0) {return "textAlignLeft";}
              }
            },
        }
    }

2、客户电量电费信息表格

这个表格和失常表格一样开发就行，只是最初一行是字体加粗，色彩有设置，在 table 上增加:cell-class-name=”setTextWeight” 属性，在办法中对 setTextWeight 进行设置即可，而后设置 text-set 款式即可。

// 设置客户电量电费信息中批发交易电费加粗显示
setTextWeight({rowIndex, columnIndex}) {if (rowIndex == 10) {return "text-set";}
},

3、客户偏差考核信息

操作：1、合并单元格，2、文案靠右显示 

// 设置第一档和第二档正偏差电价、负偏差电价靠右显示
setTextRight({rowIndex, columnIndex}) {if (rowIndex == 1 || rowIndex == 4) {if (columnIndex != 0) {return "textAlignRight";}
  }
},
// 设置第一档和第二档正偏差电价、负偏差电价合并单元格
arraySpanMethod2({rowIndex, columnIndex}) {
  // 示意行数，不蕴含表头行数
  if (rowIndex == 1 || rowIndex == 4) {
    // 去掉第一列之后的所有列进行合并
    if (columnIndex != 0) {return [1, 4];
    }
  }
},

4、客户其他费用
操作：1、合并单元格，2、文案靠左显示，3、文案色彩，宽度设置 

// 合并客户其他费用中最初两行
arraySpanMethod3({rowIndex, columnIndex}) {if (rowIndex == 4 || rowIndex == 5) {return [1, 4];
  }
},
// 设置客户其他费用中最初两行字体加粗
setCustomTextLeft({rowIndex, columnIndex}) {if (rowIndex == 4 || rowIndex == 5) {return "textCustomAlignLeft";}
},

大部分都是进行单元格合并和文案设置，element 有提供对应的属性和办法。看看效果图，页面太长，分两张截图展现：


基本上和要求的表格差不多了，大家有好的实现计划能够告知我，我也学习下，下次就不必搞这么多 table 了，以下附上源码，
