如何将数据帧数组转换为单个数据帧?[副本]

我有一个 array 被称为“的数据帧数” dataFrames “看起来像这样:

dataFrames(0)
+----------+--------------------+---------+-------------+
|Periodo   |              frutas|freq     |prods_qty    |
+----------+--------------------+---------+-------------+
|         1|Apple, Watermelon   |        1|            2|
|         1|Banana, StrawBerry  |        2|            2|
+----------+--------------------+---------+-------------+

dataFrames(1)
+----------+--------------------+---------+-------------+
|Periodo   |              frutas|freq     |prods_qty    |
+----------+--------------------+---------+-------------+
|         2|Naranjas, Fresas    |        7|            2|
|         2|Pineapple, Apples   |        9|            2|
+----------+--------------------+---------+-------------+

嗯,我需要一个单人间 dataframe 像这样:

+----------+--------------------+---------+-------------+
|Periodo   |              frutas|freq     |prods_qty    |
+----------+--------------------+---------+-------------+
|         1|Apple, Watermelon   |        1|            2|
|         1|Banana, StrawBerry  |        2|            2|
|         2|Naranjas, Fresas    |        7|            2|
|         2|Pineapple, Apples   |        9|            2|
+----------+--------------------+---------+-------------+

对于本例,数组的长度为1,但数组可以是任意大小。

有可能做到这一点。。。或者我需要将数据帧存储到配置单元表中?

提前感谢
