def find_table_in_boxes(boxes, cell_threshold=10, min_columns=2):
    for box in boxes:
        (x, y, w, h) = box
        print(box)
        col_key = x // cell_threshold

    text_boxes = [

错误

它告诉您T是一个字符串。它来自class Action<T extends Promise<string> | Observable<string> | ReadableStream<string>> { dispatcher: (x: string) => T; constructor(dist: (x: string) => T) { this.dispatcher = dist } f = (s: string) => this.dispatcher('hello' + s); } // note that x is type string in this: const promiseDispatcher = (x: string) => Promise.resolve(x) const a = new Action(promiseDispatcher); a.f("random string").then((s: string) => { // ... })，来自apply(a, 2, function(x) paste('p', parent.frame()$i[], ': ', x, sep=''))。您不能使用以下命令解包字典值：

Session::put('name','value')

尝试以下方法：

另一个选择是：

boxes
