在两个日期之间过滤 Pyspark 数据框

Question

我有一个 pyspark 数据框，如下所示。我只需要 2017-12-17 和 2017-12-19 之间的 target_date 行，这两个日期都包括在内。 输入：

+-------+-----------+------------+
|     id|target_date|order_before|
+-------+-----------+------------+
|1471783| 2017-12-16|           2|
|1471885| 2017-12-16|           2|
|1472928| 2017-12-17|           2|
|1476917| 2017-12-17|           2|
|1477469| 2017-12-18|           1|
|1478190| 2017-12-19|           4|
+-------+-----------+------------+

我需要的输出如下所示。

+-------+-----------+------------+
|     id|target_date|order_before|
+-------+-----------+------------+
|1472928| 2017-12-17|           2|
|1476917| 2017-12-17|           2|
|1477469| 2017-12-18|           1|
|1478190| 2017-12-19|           4|
+-------+-----------+------------+
