最近项目需要实现可编辑的动态多级表头表格，看了两天的文章，始终没有找到我想要的效果，在了解了render+jsx的基础用法后，自己基于element-ui封装了一个，数据格式参考element-ui table的数据。实现如下：
1.scoresTable
<script> import scoresColumn from "./scoresColumn"; export default { components: { scoresColumn }, render: function(h) { return <div className="table-control"> <el-table ref="table" size="small" {...{attrs: {data:this.tableData}}} border > { this.tableTitles.map(title => { return <scoresColumn on-dataChange={this.dataChange} {...{attrs: {column:title,unitScores: this.unitScores}}}></scoresColumn> }) } </el-table> </div>; }, props: { tableTitles: { type: Array, default: () => [] }, tableData: { type: Array, default: () => [] }, unitScores: { type: Object, default: () => {} } }, methods: { dataChange(id) { this.$emit('dataChange', id); } }, } </script> <style> .el-table th, .el-table td { text-align: center; } </style>
2.scoresColumn
<script> export default { data() { return { style: { 'min-width': "70", 'resizable': true, 'show-overflow-tooltip': true }, } }, props: { column: { type: Object }, unitScores: { type: Object, default: () => {} } }, name: "scoresColumn", render: function (h) { let scopedSlots = { default: (scope) => { let col = scope.column.property; let value = scope.row[col]; return <div id={col+scope.$index} > <p onClick={this.clickHandle}>{value}</p> </div>; } }; if (this.column.children === undefined) if (this.column.label == '序号' || this.column.label == '姓名') { return <el-table-column fixed {...{style: this.style, scopedSlots: { default: (scope) => { let value = scope.row[scope.column.property]; return <p>{value}</p>; } }}} prop={this.column.prop} label={this.column.label}> </el-table-column> }else { return <el-table-column {...{style: this.style, scopedSlots: { default: (scope) => { let value = scope.row[scope.column.property]; if (/\((?=\d)|(^总计$)/g.test(this.column.label)) { let col = scope.column.property; return <div id={col+scope.$index} > <p onClick={this.clickHandle}>{value}</p> </div>; }else return <p>{value}</p>; } }}} prop={this.column.prop} label={this.column.label}> </el-table-column> } let buildTitles = (childList) => { let children = []; childList.map(child => { if (child.children != undefined && child.children.length > 0) { children.push(<el-table-column {...{style: this.style}} label={child.label}> {buildTitles(child.children)} </el-table-column>) } else { children.push( <el-table-column {...{style: this.style, scopedSlots: scopedSlots}} label={child.label} prop={child.prop}> </el-table-column>) } }); return children; }; return <el-table-column {...{style: this.style}} label={this.column.label} prop={this.column.prop}> {buildTitles(this.column.children)} </el-table-column>; }, methods: { blurHandler(e) { let parent = e.target.parentNode; let child = parent.firstElementChild; let p = document.createElement('p'); let value = child.value.match(/^\d*(\.{1}\d+)?/)[0]; if (value == '' || value == null) { value = 0; } p.innerHTML = value; p.addEventListener('click', this.clickHandle, false); child.replaceWith(p); this.$emit('dataChange', parent.id); }, clickHandle(e) { let parent = e.target.parentNode; let child = parent.firstElementChild; let input = document.createElement('input'); input.style.lineHeight = '23px'; input.style.textAlign = 'center'; input.style.fontSize = '12px'; input.style.height = '23px' input.style.width = '100%'; input.value = child.innerHTML; input.addEventListener('blur', this.blurHandler, true); input.addEventListener('keyup', this.keyUpHandler, false); child.replaceWith(input); input.focus(); }, keyUpHandler(e) { let input = e.target; let parent = input.parentNode; let property = parent.id.replace(/\d/g, ''); let value = input.value.replace(/[^\d\.]/g,''); if (Math.min(this.unitScores[property],value) != value) { value = this.unitScores[property]; } input.value = value; } } } </script> <style scoped> </style>
