制表符/以编程方式更正 table 数据(从 HTML <table> 加载)

Tabulator / programmatically correct table data (loaded from HTML <table>)

Tabulator 是从 unknown HTML <table>(具有 TH headers,因此所有列都有名称)创建的。

因此,无法触发任何 mutatorcallback... 除了 htmlImported:function().

因为 HTML <table> 包含格式错误的 DATE 值,我需要访问所有 rows 中的所有 fields 来发现并更正这些。

整个代码为:

<!DOCTYPE html>
<html><head><meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://unpkg.com/tabulator-tables@4.3.0/dist/css/">
<script type="text/javascript" src="https://unpkg.com/tabulator-tables@4.3.0/dist/js/tabulator.min.js"></script>
</head><body>
<table id="tablexxx">
 <tr>
  <th>Name</th><th>Favorite Color</th><th>date</th></tr>
 <tr><td>Bob</td><td>Yellow</td><td>1/1/2001</td>
 </tr>
 <tr><td>Michelle</td><td>Purple</td><td>2/1/2000</td>
 </tr>
</table>
<div id="tablexxx"></div>

<script>
var tablexxx = new Tabulator("#tablexxx", {});

var rows = tablexxx.getRows();
rows.forEach(function(row)
{ var rowData = row.getData();
  rowData.forEach(function(cell) // <<< HOW TO DO IT RIGHT???
  {
    // get row field NAME
    var field = cell.name;       // <<< HOW TO DO IT RIGHT???
    if(field.indexOf("date") >= 0)
    {
       // get colum field VALUE
       var date = cell.value;   // <<< HOW TO DO IT RIGHT???

       // make new value using proper format
       var ndate = date[0] + date[1] + date[2]; // TODO

       // update row with {"date":"01/02/2000"}
       row.update("{" + field + ":" + ndate + "}"); 
    }
  });
});
</script></body></html>

有人可以告诉我如何 "DO IT RIGHT" 上面指定的 <script> 部分滞后吗?

我希望我明白你想要完成什么...

如果 < 10,则用 0 填充日和月。

首先获取包含数据字段的列,然后遍历该列中的每个单元格,拆分日期并更新单元格。 我实际上不知道为什么 table 中有一个空行(这就是 if (value) 的用途)。是tabulator插入的东西

function pad(num, size) {
    var s = num + "";
    while (s.length < size) s = "0" + s;
    return s;
}

var tablexxx = new Tabulator("#tablexxx", {});
var dateColumn = tablexxx.getColumn("date");
for (var cell of dateColumn.getCells()) {
  var value = cell.getValue();
  if (value) {
    value = value.split("/")
    cell.setValue(pad(value[0], 2) + "/" + pad(value[1], 2) + "/" + value[2]);
  }
}
