使用添加列和行创建一个动态表，该表取决于jQuery或JavaScript中的数据

Question

我有一个我希望使其更具动态的表。如何将此代码更改为动态表，例如。

当前版本和修订日期列的示例。

如果当前版本和修订日期 它将创建另一列以使其3或4等当前版本修订日期列。

备注列的示例。

如果备注列的数据添加了另一列备注列，该列是第一个，第二，第3，第4，第四...等等。

请参阅下面的示例输出。

<table border="2" style="width:100%;">
            <thead>
                <tr>
                    <th rowspan="2">ID</th>
                    <th rowspan="2">Document Name</th>
                    <th rowspan="2">Document ID</th>
                    <th>Current Version</th>
                    <th>Current Version</th>
                    <th colspan="2">Remarks</th>
                    <th rowspan="2">Signature</th>
                </tr>
                <tr>
                    <th>Revision Date</th>
                    <th>Revision Date</th>

        </table>

var APIData = [{ Section_No: '4.1',

我建议您使用JSViews软件包 - 它非常适合您的任务。

我已经准备了一个示例，使用您的示例数据扩展为2行：jsfiddle

这是jsviews/jsrender模板代码：

<table border="1" style="width:100%;">
    <thead>
        <tr>
            <th rowspan="2">ID</th>
            <th rowspan="2">Document Name</th>
            <th rowspan="2">Document ID</th>
            {{for ~makeArray(maxVersions)}}
            <th>Current Version</th>
            {{/for}}
            <th colspan="{{:maxRemarks}}">Remarks</th>
            <th rowspan="2">Signature</th>
        </tr>
        <tr>
            {{for ~makeArray(maxVersions)}}
            <th>Revision Date</th>
            {{/for}}
            {{for ~makeArray(maxRemarks)}}
            <th rowspan="2">{{:~getNumberWithOrdinal(#index+1)}}</th>
            {{/for}}
        </tr>
    </thead>
    <tbody id="resultAppend">
    {{for rows ~maxVersions = maxVersions ~maxRemarks = maxRemarks}}
        <tr>
            <td rowspan="2">{{:Section_No}}</td>
            <td rowspan="2">{{:Document_Title}}</td>
            <td rowspan="2">{{:Document_ID}}</td>
            {{for Revisions}}
            <td>{{:#data.No}}</td>
            {{/for}}
            {{for ~makeArray(~maxVersions - Revisions.length)}}
            <td></td>
            {{/for}}
            {{for remarks}}
            <td rowspan="2">{{:#data}}</td>
            {{/for}}
            {{for ~makeArray(~maxRemarks - remarks.length)}}
            <td rowspan="2"></td>
            {{/for}}
            <td rowspan="2">{{:Signature}}</td>
        </tr>
        <tr>
            {{for Revisions}}
            <td>{{:#data.Approval_Date}}</td>
            {{/for}}
            {{for ~makeArray(~maxVersions - Revisions.length)}}
            <td></td>
            {{/for}}
        </tr>
    {{/for}}    
    </tbody>
</table>

和JS：

var APIData = [
  { 
    Section_No: '4.1',
    Document_Title: 'Sample Document Title',
    Document_ID: 'QM-CI-001',
    Revisions: [ 
      { No: '01', Approval_Date:'8/23/2017' },
      { No: '02', Approval_Date: '3/12/2018' }, 
    ], 
    remarks: [ 'OK', 'OK' ],
    Signature: 'Signature' 
  },
  { 
    Section_No: '4.2',
    Document_Title: 'Sample Document Title 2',
    Document_ID: 'QM-CI-002',
    Revisions: [ 
      { No: '01', Approval_Date: '3/12/2018' }, 
    ], 
    remarks: [ 'OK', 'OK', 'OK' ],
    Signature: 'Signature2' 
  },
];
$.views.helpers({
  getNumberWithOrdinal: function(n) {
    var s=["th","st","nd","rd"],
    v=n%100;
    return n+(s[(v-20)%10]||s[v]||s[0]); },
  makeArray: function(count) {
    var array = [];
    if(count) { array[count-1] = {}; }
    return array;
  }
});
var template = $.templates("#theTmpl");
var data = {
  maxVersions: 1,
  maxRemarks: 1,
  rows: APIData
};
APIData.forEach(function(row){
  var versions = row.Revisions.length;
  if( versions > data.maxVersions) { data.maxVersions = versions; }
  var remarks = row.remarks.length;
  if( remarks > data.maxRemarks) { data.maxRemarks = remarks; }
});
template.link("#result", data);
