我创建了包含3列的表：DocumentID，SentenceId，Sentence。我想自己分配DocumentId，SentenceID增加自身，并将文本文件中的数据插入到省略第一个数字的列句中。例如，文本文件中有一个文本：
0,189 A few years ago , when I was looking at middle schools for my daughter.
190,412 Having reported on a vogue for single-sex classrooms in the nineties.
在表格中导入此文本文件后，我希望得到如下内容：
DocumentID | SentenceID | Sentence
123 | 1 | A few years ago, when...
123 | 2 | Having reported on a vogue....
