如何在制表符中过滤树结构中的子项？

我尝试打电话setFilter在我的制表符树结构上运行函数，以过滤掉项目。它似乎只过滤掉顶级父母。知道如何使其适用于任何级别（任何儿童或家长）吗？http://tabulator.info/docs/4.1/tree没有过多说明过滤的工作原理。

Function

table.setFilter('id', '=', 214659)没有返回任何东西...

经过一番搜索后发现了一个扩展lodash图书馆叫deepdash它具有深层过滤并且效果很好。

您将有 2 个新的依赖项，但我认为它将满足您的目的。 检查有关如何安装它们的文档here

在此处的代码片段中，您可以在日志中看到结果。我也做了一个沙箱here

这是一个或多个 id 列表。

如果您只需要一个值，请更改条件。return _.indexOf(idList, value.id) !== -1; to return id===value.id; where id是你的id多变的

另外，在查看 Tabulator 的文档后，只有一级过滤，即使您编写自己的自定义过滤器也无济于事，因为它期望一个 bool 值来渲染行或不渲染行。但仅适用于第一级，因此如果父级不是您所寻找的，则子级将被忽略。您唯一的选择是过滤制表符之外的数据。
