表格的四列（x，y，z，值）到矩阵表

Question

我想将四列中的数据转换为矩阵表。我尝试过使用OFFSET功能，但是我的数据太大了（大约100,000个单元格）并且崩溃了。

所以，我想通过宏来尝试这样做，你能建议怎么做吗？或者你有更好的建议，那将是伟大的。

PS。我使用了此网站here中的OFFSET公式。

Answer 1

使用以上类型的齿轮进行ROWS，柱的颜色和Σ值的总和：

隐藏顶行，报表布局以表格形式显示，删除所有小计和总计，重新排列列和行的顺序，设置为显示0的空单元格，隐藏展开/折叠按钮，重复所有项目标签设置为*，并添加了边框。

为了显示0的行，我在源数据中添加了Bus / Green / Manual（颜色（绿色）以避免（空白）作为额外列）。

*在Excel 2007中不可用。要重复Excel 2010之前版本的项目标签，标准做法是复制PT和选择性粘贴，使用Go To Special，Blanks选择空白并填充空白然后=，向上， Ctrl + 输入。

Answer 2

有趣的问题！因为您遇到涉及数据大小的问题，所以我试图避免使用字典之类的对象（我不知道字典可以容纳多少）。相反，我创建了一个程序，可以跟踪非常少的数据，但最终会不断地从文件读取/写入：它会非常慢，但它适用于非常大的文件。

无论如何，请尝试将以下代码复制并粘贴到VBA模块中，然后在您的文件上运行它。您可能需要更改行和列的某些值。

编辑：我为你给出的示例图片工作了，但它很乱。我明天会试着让它更清楚（g2g）
编辑：它已被更新！仔细评论等，无论你喜欢什么都很容易修改。

摘要

• 在数据表下面构建矩阵表
• 遍历数据表的行并将它们添加到矩阵表
• 如果矩阵表中没有数据的行或列，请创建它，否则放在现有的
中
