先上效果图：

实现代码：利用lb-element-table实现。

template中：

{{table.indicatorType}}

注：其中merge中的数组是你需要合并的列的属性名。

data中定义column：

column = [

{

prop: "project",

label: "项目"

},

{

prop: "indicatorName",

label: "指标"

}

];

data中定义tableData的值：

listData: [

{

indicatorType: "指标分类1",

tableData: [

{

project: "工艺流程名称2",

indicatorName: "指标名称2",

name: "2019-01-01",

value1: "8",

value2: "90",

value3: "14",

value4: "14",

value5: "10",

value6: "17",

value7: "1",

unit: "kg"

},

{

project: "工艺流程名称2",

indicatorName: "指标名称2",

name: "2019-01-02",

value1: "10",

value2: "1",

value3: "140",

value4: "100",

value5: "10",

value6: "14",

value7: "10"

},

{
