如何在 xlwt 中编写具有多列的单元格？

Question

我想写一个这样的表格：

----------------
| Long Cell    |
----------------
| 1    | 2     |
----------------

单元格Long Cell怎么写？谢谢。

我试过这样做：

sheet.write(0, 0, 'Long Cell')
sheet.write(1, 0, 1)
sheet.write(1, 1, 2)

但结果是这样的：

--------------------
| Long Cell |      |
--------------------
| 1         | 2    |
--------------------

据我所知，这没有文档记录 - 您必须阅读源代码才能找到它。 Worksheet 类有两种方法可以做到这一点，write_merge 和 merge。 merge 获取现有单元格并将它们合并，而 write_merge 写入标签（就像 write）然后执行与 merge 相同的操作。

两者都将单元格合并为r1, r2, c1, c2，并接受可选的style 参数。

根据您的示例，这将是最简单的调用：

sheet.write_merge(0, 0, 0, 1, 'Long Cell')
sheet.write(1, 0, 1)
sheet.write(1, 1, 2)

更明确地说明调用的工作原理：

top_row = 0
bottom_row = 0
left_column = 0
right_column = 1
sheet.write_merge(top_row, bottom_row, left_column, right_column, 'Long Cell')

或者，使用merge:

sheet.write(top_row, left_column, 'Long Cell')
sheet.merge(top_row, bottom_row, left_column, right_column)

merge 源码中有一些 cmets 指出了潜在的问题：

    # Problems: (1) style to be used should be existing style of
    # the top-left cell, not an arg.
    # (2) should ensure that any previous data value in
    # non-top-left cells is nobbled.
    # Note: if a cell is set by a data record then later
    # is referenced by a [MUL]BLANK record, Excel will blank
    # out the cell on the screen, but OOo & Gnu will not
    # blank it out. Need to do something better than writing
    # multiple records. In the meantime, avoid this method and use
    # write_merge() instead.

但对于这样一个简单的案例来说，它会很好。
