el-table合计行更新问题

说明：在使用el-table自带的底部合计功能时，初始界面不会显示合计内容

解决方案：使用 doLayout()方法

updated() { 		this.$nextTick(() => { 			this.$refs['inventorySumTable'].doLayout(); 		}); 	}, 

完整代码：

 // show-summary：展示合计行  // summary-method:自定义合计方法  // ref="inventorySumTable"：绑定表格             <el-table 				border 				height="100%" 				:data="tableList" 				v-loading="tableLoading" 				show-summary 				:summary-method="getSummaries" 				ref="inventorySumTable" 				:cell-style="changeCellStyle" 			> 				<el-table-column 					label="序号" 					prop="index" 					type="index" 					width="55" 					align="center" 					header-align="center" 				></el-table-column> 				<el-table-column 					label="使用单位(科室)" 					prop="useDept" 					align="center" 					header-align="center" 					show-overflow-tooltip 				></el-table-column> 				<el-table-column 					label="资产分类" 					prop="typeName" 					align="center" 					header-align="center" 					show-overflow-tooltip 				> 				</el-table-column> 				<el-table-column 					label="折旧合计" 					prop="sumDepreciation" 					align="center" 					header-align="center" 					show-overflow-tooltip 				></el-table-column> 			</el-table>    //定义合计的方法         getSummaries(param) { 			const { columns, data } = param; 			const sums = []; 			columns.forEach((column, index) => { 				if (index === 0) { 					sums[index] = '合计'; 					return; 				} 				const values = data.map(item => Number(item[column.property])); 				if ( 					!values.every(value => { 						return isNaN(value); 					}) 				) { 					console.log(sums, column.property, 226); 					if (column.property == 'sumDepreciation') { 						sums[index] = values.reduce((prev, curr) => { 							const value = Number(curr); 							if (!isNaN(value)) { 								return prev + curr; 							} else { 								return prev; 							} 						}, 0); 					} 					if (column.property == 'sumDepreciation') { 						return (sums[index] = this.formatePrice(sums[index])); 					} 				} else { 					sums[index] = ''; 				} 			});  			return sums; 		},
