动态编辑表格（支持自定义编辑组件）

<template>
  <div
    class="edit-cell"
    @click="onFieldClick"
  >
    <el-tooltip
      v-if="!editMode && !showInput"
      :placement="toolTipPlacement"
      :open-delay="toolTipDelay"
    >
      <div
        tabindex="0"
        @keyup.enter="onFieldClick"
      >
        <slot name="content" />
      </div>
    </el-tooltip>
    <component
      :is="editableComponent"
      v-if="editMode || showInput"
      ref="input"
      v-bind="$attrs"
      v-model="model"
      @focus="onFieldClick"
      @keyup.enter.native="onInputExit"
      v-on="listeners"
    >
      <slot name="edit-component-slot" />
    </component>
  </div>
</template>
<script>
export default {
	name: "EditableCell",
	inheritAttrs: false,
	props: {
		value: {
			type: String,
			default: ""
		},
		// toolTipContent: {
		// 	type: String,
		// 	default: this.value
		// },
		toolTipDelay: {
			type: Number,
			default: 5000000
		},
		toolTipPlacement: {
			type: String,
			default: "top-start"
		},
		showInput: {
			type: Boolean,
			default: false
		},
		editableComponent: {
			type: String,
			default: "el-input"
		},
		closeEvent: {
			type: String,
			default: "blur"
		}
	},
	data() {
		return {
			editMode: false
		};
	},
	computed: {
		model: {
			get() {
				return this.value;
			},
			set(val) {
				this.$emit("input", val);
			}
		},
		listeners() {
			return {
				[this.closeEvent]: this.onInputExit,
				...this.$listeners
			};
		}
	},
	methods: {
		onFieldClick() {
			this.editMode = true;
			this.$nextTick(() => {
				let inputRef = this.$refs.input;
				if (inputRef) {
					inputRef.focus();
				}
			});
		},
		onInputExit() {
			this.editMode = false;
		},
		onInputChange(val) {
			this.$emit("input", val);
		}
	}
};
</script>

</style>

• 在表格中使用时把渲染的内容放在content插槽中

          <Editable-cell
            v-model="row.companyLevel"
            slot-scope="{ row }"
            :show-input="row.editMode"
            editable-component="el-select"
            close-event="change"
          ></Editable-cell>
// 用插槽来把数据给到组件，使用的时候要记得给table绑定的数据加上是否显示编辑组件的值editMode，涉及到数据的保存修改时要把这个editMode删除掉，避免发起请求时作为不必要的字段传给接口

• 可以用map的方法把editMode添加到绑定数据中

mounted: async function () {
		await this.getCompanyTable();
		this.tableData = this.tableData.map(row => {
			return {
				...row,
				editMode: false
			};
		});
	},
