禁止特定行选择
本示例展示了如何使用 select.selectable 选项禁用特定行的行选择。这必须作为一个函数给出，然后检查行以查看是否应该可选（通常此确定将基于行中的数据）。如果不行，则 Select 将忽略此行的操作。
在本示例中，所有位置为“New York”的行都是不可选择的。为了直观地显示这一点，使用一点 CSS 来淡化这些行（通过 rowCallback 处理程序添加的类）。这是可选的，但它给最终用户一个直观的提示。如果你正在为行选择使用复选框，则不符合可选要求的行不会显示复选框。

下面显示的 JavaScript 用于初始化此示例中显示的表格
$('#example').DataTable({ rowCallback: function (tr, rowData) { if (rowData[2] === 'New York') { $(tr).addClass('unselectable'); } }, select: { selectable: function (rowData) { return rowData[2] !== 'New York'; } } });
new DataTable('#example', { rowCallback: function (tr, rowData) { if (rowData[2] === 'New York') { tr.classList.add('unselectable'); } }, select: { selectable: function (rowData) { return rowData[2] !== 'New York'; } } });
除了以上代码之外，还加载了以下 JavaScript 库文件以用于此示例
下面显示的 HTML 是原始 HTML 表格元素，在 DataTables 增强该元素之前
为了正确显示表格，本例使用了一些额外的 CSS，超出了库文件（如下所示）加载的内容。下面显示了所使用的额外 CSS
tr.unselectable { opacity: 0.5; }
为了给表格提供样式，加载了以下 CSS 库文件以用于此示例
此表格通过 Ajax 加载数据。下面显示了已加载的最新数据。此数据将随着加载的任何其他数据自动更新。
下面显示了用于对该表格执行服务器端处理的脚本。请注意，这只是使用 PHP 的示例脚本。服务器端处理脚本可以用任何语言编写，使用 DataTables 文档中描述的协议。
