前端-layui动态渲染表格行列与复杂表头合并

news2024/9/20 22:00:44

说在前面：
最近一直在用layui处理表格
写的有些代码感觉还挺有用的，顺便记录下来方便以后查看使用；

HTML处代码

拿到id 渲染位置表格

 <div class="layui-table-body salaryTable">
                <table class="layui-table" id="ID-table-salary-parse" style="display:block"></table>
            </div>

CSS

  .layui-table th {
             background-color: rgb(199 217 234 / 78%); /* 设置表头的背景颜色 */
             color: #2e2e2e; /* 设置表头的文本颜色 */
             font-weight: bold;
         }

        .layui-table tbody tr:nth-child(odd) {
            background-color: #ffffff; /* 设置奇数行的背景颜色 */
        }

        .layui-table tbody tr:nth-child(even) {
            background-color: rgba(239, 239, 239, 0.94); /* 设置偶数行的背景颜色 */
        }
        .layui-table td, .layui-table th {
            border: 1px solid #e6e6e6; /* 边框颜色 */
        }
        .layui-table td, .layui-table th {
            border-width: 2px; /* 设置双边框效果 */
        }

重点来了
JS代码


var backData = {};
var backData3 = {};
layui.use('table', function () {
    getStudentTaskData()

    function getStudentTaskData() {
        ajaxBase.getSelectInfo(false, function (jsonData) {
            if (jsonData['单据json']) {
                backData = jsonData['代扣项目'];
                backData3 = jsonData['工资薪酬计算表'];
            }
        })
    }

    var datas = []
    $.each(backData3, function (index, item) {
        var coll = {};
        for (key in item) {
            coll[key.split("、")[1]] = item[key];
        }
        datas.push(coll);
    })
    var table = layui.table;
    var colLists = [];
    for (key in backData[0]) {
        var colList = {};
        colList['field'] = key;
        colList['title'] = key;
        colList['align'] = 'center';
        colList['minWidth'] = '122';
        colLists.push(colList);
    }
    colLists.sort();
    // 渲染
    table.render({
        elem: '#ID-table-demo-parse'
        , data: backData
        , cols: [colLists]
        , height: 100
    });
    colLists = [];
    var colls = [];
    const site = 0;
    var colList = {};
    for (key in backData3[0]) {
        colList[key.split("、")[0]] = key.split("、")[1]
    }
    for (key in colList) {
        var coll = {};
        if (colList[key].includes('代扣项目')) {
            coll['field'] = colList[key];
            coll['edit'] = 'text';
            coll['title'] = colList[key].split("-")[1];
            coll['align'] = 'center';
            colls.push(coll);
            // colLists.push(coll);
        } else {
            coll['field'] = colList[key];
            coll['title'] = colList[key];
            coll['edit'] = 'text';
            coll['rowspan'] = 2;
            coll['align'] = 'center';
            colLists.push(coll);
            if (colList[key].includes('收入总额')) {
                var colll = {};
                colll['field'] = '代扣项目';
                colll['title'] = '代扣项目';
                colll['align'] = 'center';
                colll['colspan'] = 5;
                colLists.push(colll);
            }
        }
    }
    //console.log('colLists', colLists)
    // 渲染
    table.render({
        elem: '#ID-table-salary-parse'
        , data: datas
        , cols: [colLists, colls]
        , height: 350

    });
});
