我有一个带有2列的antd表，我需要在第一列上进行过滤，并在第二列上搜索文本。
根据我的代码，该应用程序呈现良好。请注意，标签字段是一个json数组，而不是文本字段，因此我想这与错误有关。
更新了1个代码。

},{

...this.getColumnSearchProps('Tags'),
render: Tags => (
<span>
{Tags && Tags.map(tag => {
let color = tag.length > 5 ? 'geekblue' : 'green';

onChange: (selectedRowKeys) => {
this.props.onRowSelect(selectedRowKeys);
}
};
return (
<div>
<Button onClick={this.clearFilters}>Clear filters</Button>
<Button onClick={this.clearAll}>Clear filters and sorters</Button>
<Table rowSelection={rowSelection} columns={columns} dataSource={this.state.data} onChange={this.handleChange} />
</div>
);
}
}
export default ListPageTemplatesWithSelection;
但是，当我添加以下行时:
...this.getColumnSearchProps('Tags'),然后我得到这个错误
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

最佳答案
很难从您提供的错误中猜测出了什么问题。因此，我能做的最好的事情就是指出您应该注意的几件事。getColumnSearchProps()的呈现方法是错误的。如果文本是null(由于一行没有任何标签)，它将尝试将其转换为字符串并崩溃。为了避免这种情况，请在渲染之前检查text是否存在:
render: text =>
text ? (
<Highlighter
highlightStyle={{ backgroundColor: "#ffc069", padding: 0 }}
searchWords={[this.state.searchText]}
autoEscape
textToHighlight={text.toString()}
/>
) : null
onFilter方法也是如此:onFilter: (value, record) =>
record[dataIndex]
? record[dataIndex]
.toString()
.toLowerCase()
.includes(value.toLowerCase())
: false,
您有两种
render方法来呈现“标签”列。一个在getColumnSearchProps()内部，另一个在...this.getColumnSearchProps('Tags')调用之后。这应该没问题，因为后者会覆盖前一个。再说一次，如果您不需要它，为什么还要宣布它为珍贵？希望这可以帮助。
