如何在xlwt中编写多列的单元格？

Question

我想写一张这样的表：

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

如何编写单元格Long Cell？感谢。

我试图这样做：

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

但最终结果如下：

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

据我所知，这没有记录 - 您必须阅读源代码才能找到它。 Worksheet类有两种方法可以执行此操作，write_merge和merge。 merge获取现有单元格并合并它们，而write_merge会写一个标签（就像write），然后执行相同的内容merge。

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

从您的示例中，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)

更明确地说明呼叫的工作原理：

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在来源中有一些评论指出了潜在的问题：

    # 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.

但对于像这样的简单案例，这样会很好。
