javascript - Bootstrap Datatables Javascript - 长度菜单和导出按钮相互挤压 - 想要在两者之间创建换行符

标签 javascript html jquery bootstrap-4 datatables

我有一个正在开发的可搜索表，用户需要能够在其中导出他们的结果，而且还可以选择他们看到的结果数量。问题是一切看起来都太挤在一起了。我希望能够添加换行符、段落或 div 来分隔内容。基本上，我想要这个:
项目搜索显示 [Number] 个条目
[复制] [Excel] [CSV] [PDF] [列可见性]
[我的 table ]
我该怎么做呢？我不能在这里依赖我可信赖的 BR 和 P html 标签，但我想弄清楚这一点。

$(document).ready(function() {
  $('#example').DataTable({
    "lengthMenu": [10, 25, 50, 75, 100],
    dom: 'lBfrtip',
    "columnDefs": [{
        "targets": [],
        "visible": false,
        "searchable": false
      },
      {
        "targets": [],
        "visible": false
      }
    ],

    buttons: [{
        extend: 'copyHtml5',
        exportOptions: {
          columns: ':visible',
          format: {
            body: function(data, row, column, node) {
              var text = node.textContent;
              return column === 10 ? text.replace(/Open$/, '').trim() : data;
            }
          }
        }
      },
      {
        extend: 'excelHtml5',
        exportOptions: {
          columns: ':visible',
          format: {
            body: function(data, row, column, node) {
              var text = node.textContent;
              return column === 10 ? text.replace(/Open$/, '').trim() : data;
            }
          }
        }
      },
      {
        extend: 'csvHtml5',
        exportOptions: {
          columns: ':visible',
          format: {
            body: function(data, row, column, node) {
              var text = node.textContent;
              return column === 10 ? text.replace(/Open$/, '').trim() : data;
            }
          }
        }
      },

            }
          }

最佳答案

如果我理解正确的话，我只添加了这个 CSS 规则:

.dataTables_length {
    position: relative;
    float: none !important;
    text-align: center;
}
显然，如果您不想要 Show [Number] Entries水平居中，只需删除 text-align: center;
