PowerShell：如果 B 列值为 "X"，则使用 A 列前一行数据的数据填充 A 列空行
PowerShell: populate column A null rows with data from previous column A row data, if Column B value is "X"
我有一个格式奇怪的 csv 文件需要调整，我可以使用 powershell 获得一些帮助。我通常很清楚从哪里开始，但是我对如何根据具有“销售订单”的 B 列从前一行到下一行的 A 列迭代数据有点不知所措，并且只有如果 Column A 字段为 Null，则执行此操作，然后使用填充的下一行继续下行。
这是 csv 图片的样子：
这是实际数据：
