Question

我正在使用带有子组件的反应表 7。我已经使用 React Table 7 API examples 中提供的示例构建了我的表。但是，我收到警告，

React Hook React.useCallback has missing dependencies: 'props.setStatus' and 'statusColumns'. Either include them or remove the dependency array

依赖项在 return 语句之前被声明为变量，但在函数内。列名被正确识别和实现，那么为什么我会收到此警告以及如何防止这种情况发生？

代码实现如下：

const EnforcementActionsTable = (props) => {
  const columns = [
    {
      Header: () => null, // No header
      id: "expander", // It needs an ID
      width: 30,
      Cell: ({ row }) => (
        <span {...row.getToggleRowExpandedProps()}>
          {row.isExpanded ? (
            <FontAwesomeIcon className="font-icon" icon={faCaretDown} />
          ) : (
            <FontAwesomeIcon className="font-icon" icon={faCaretRight} />
          )}
        </span>
      )
    },
    {
      Header: "Edit Action",
      id: "eaId",
      Cell: (row) => {
        return (
          <div className="text-center">
            <FontAwesomeIcon
              className="font-icon"
              icon={faEdit}
              onClick={() => {
                props.handleShow(props.id);
                props.setItem(row.original);
              }}
            />
          </div>
        );
      },
      width: 75,
      disableFilters: true

export default EnforcementActionsTable;

Answer 1

将 props.setStatus 和 statusColumns 添加到依赖项数组。

renderRowSubComponent={React.useCallback(
          ({ row }) =>
            row.original.enforcementActionStatusList.length > 0 ? (
              <Table
                data={row.original.enforcementActionStatusList}
                columns={statusColumns}
                rowOnClick={true}
                rowClickHandler={props.setStatus}
              />
            ) : (
              "No data"
            ),
          [statusColumns,props.setStatus]
        )}

根据钩子 documentation

<块引用>

useCallback 将返回回调的记忆版本，该版本仅在依赖项之一发生更改时才会更改。这在将回调传递给依赖引用相等的优化子组件时很有用，以防止不必要的渲染（例如 shouldComponentUpdate）。

React Hook React.useCallback 缺少依赖项
