1. form定义时，需要定义tableData

const supplyForm = ref({ tableData: [] })

const supplyFormRules = reactive({
	bomNumber: [{ required: true, message: '请填写物料编号', trigger: 'blur' }],
	bomName: [{ required: true, message: '请填写名称', trigger: 'blur' }]
})

2. html绑定

		<el-form :model="supplyForm" ref="supplyFormRef" inline-message class="supply-form-table">
			<el-table
				:data="supplyForm.tableData"
				border
				style="width: 100%"
				@cell-click="handleCellEnter"
				scrollbar-always-on
				highlight-current-row
				empty-text="暂无数据"
				max-height="420"
				stripe
				:header-cell-style="{ background: '#f5f7fa' }"
				:row-style="{ 'background-color': '#fdf6ec' }"
			>
				<el-table-column label="序号" prop="bomNo" width="80">
					<template v-slot="scope"> {{ scope.$index + 1 }}</template>
				</el-table-column>
				<el-table-column prop="bomNumber" label="物料编号">
					<template #default="scope">
						<el-form-item :prop="`tableData.[${scope.$index}].bomNumber`" :rules="supplyFormRules.bomNumber">
							<el-input class="cell-input" v-model="scope.row.bomNumber" size="small"
						/></el-form-item>
					</template>
				</el-table-column>
				<el-table-column prop="bomName" label="名称">
					<template #default="scope">
						<el-form-item :prop="`tableData.[${scope.$index}].bomName`" :rules="supplyFormRules.bomName">
							<el-input class="cell-input" v-model="scope.row.bomName" size="small"
						/></el-form-item>
					</template>
				</el-table-column>
				<el-table-column label="操作">
					<template #default="scope">
						<el-button link @click="() => deleteSupplyRow(scope.row)">删除</el-button>
					</template>
				</el-table-column>
			</el-table>
		</el-form>

3. tableData赋值

supplyForm.value.tableData.push(bomItem)
