Question

我使用了jquery dataTable，并且我有如下要求：

如果我拖动行（- BRAND NAME:....），那么它应该只在行之间以及所有内容之间拖动。
如果我拖动行组的内容，则它不应与其他组重叠。

这是我到目前为止所做的：

HTML：

<table id="example">
    <thead>
        <tr>
            <th>Name</th>
            <th>type</th>
            <th>age</th>

        </tr>
    </thead>

    <tbody id="sortable">
<tr id="1">
    <td>Name</td>
    <td>Type1</td>
    <td>Age</td>
</tr>        
<tr id="2">
    <td>Name</td>
    <td>Type1</td>
    <td>Age</td>
</tr>        
<tr id="3">
    <td>Name</td>
    <td>Type2</td>
    <td>Age</td>
</tr>        
<tr id="4">
    <td>Name</td>
    <td>Type2</td>
    <td>Age</td>
</tr> 
    </tbody>
</table>

jQuery：

var table = $('#example').DataTable({
"searching": false,
            "paging": false,
            "info": false,
            "order": [[0, "asc"]],
            drawCallback: function (settings) {
                var api = this.api();
                var rows = api.rows({ page: 'current' }).nodes();
                var last = null;
                api.column(1, { page: 'current' }).data().each(function (group, i) {
                    if (last !== group) {
                        $(rows).eq(i).before(
                            '<tr class="groups"><td class="tdgroups" colspan="22" style="Cursor:hand !important;BACKGROUND-COLOR:rgb(237, 208, 0);font-weight:700;color:#006232;">' + '- BRAND NAME: ' + group + '</td></tr>'
                        );
                        last = group;
                    }
                });
            }
});

$("#sortable").sortable();
$("#sortable").disableSelection();

您可以稍微更改标记。将每个行组放在单独的<tbody>中并使其可排序。

var table = $('#example').DataTable({
  "searching": false,
  "bSort": false,
  "paging": false,
  "info": false,
});
$("#example>tbody").sortable({
  items: "tr:not(.group-row)"
});
$("#example").sortable({
  items: "tbody"
}).disableSelection();

table.dataTable tbody tr.group-row {
  cursor: move;
  background-color: rgb(237, 208, 0);
  font-weight: 700;
  color: #006232;
}

受Munim Munna的答案启发，我创建了一个仅通过使用javascript / jquery自动修改表结构的版本。

let table = $('#example').DataTable({
  "searching": false,
  "sort": false,
  "order": [[1, "asc"], [0, "asc"]],
  "paging": false,
  "info": false,
  drawCallback: function (settings) {
    let api = this.api();
    let rows = api.rows({ page: 'current' }).nodes();
    if ($(rows).parent().is("tbody")) {
      $(rows).unwrap();
    }
    let last = null;
    let group_index = -1;
    api.column(1, { page: 'current' }).data().each(function (group, i) {
      if (last !== group) {
        // make previous group sortable
        if (last) {
          $("#example > tbody[data-group='" + group_index + "']").sortable({
            items: "tr.group-row",
            containment: "#example > tbody[data-group='" + group_index + "']",
            opacity: 0.75
          });
        }
        group_index++;
        // add group-header before new group
        $(rows).eq(i).before(
            '<tbody data-group="' + group_index + '"><tr class="group-header"><td colspan="3">' + '- BRAND NAME: ' + group + '</td></tr></tbody>'
        );
        last = group;
      }
      // modify row and append to tbody
      $(rows).eq(i).attr('data-group', group_index).addClass('group-row').appendTo("tbody[data-group='" + group_index + "']");
    });
    // make last group also sortable
    $("#example > tbody[data-group='" + group_index + "']").sortable({
      items: "tr.group-row",
      containment: "#example > tbody[data-group='" + group_index + "']",
      opacity: 0.75
    });
    // make the tbody-elements sortable and disable selection in table
    $("#example").sortable({
      items: "tbody",
      placeholder: "tbody-placeholder",
      forcePlaceholderSize: true,
      opacity: 0.75
    })
    .disableSelection();
  }
});

table.dataTable tbody tr.group-header {
  cursor: move;
  background-color: rgb(237, 208, 0);
  font-weight: 700;
  color: #006232;
}

table.dataTable .tbody-placeholder {
  display: table-row;
  height: 50px;
}
