使用openpyxl或xl *或xlsxwriter在工作簿中移动工作表? [英] Move a worksheet in a workbook using openpyxl or xl* or xlsxwriter?

问题描述

我已阅读 openpyxl ， xlwt ， xlutils ， xlsxwriter .我找不到在 Excel工作簿中移动工作表的方法.测试在末尾添加了一个工作表.

I've read the docs for, openpyxl, xlwt, xlrd, xlutils, xlsxwriter. I don't find a way to move a sheet in an Excel workbook. Tests added a worksheet to the ends.

具体来说，我有各种各样的日历，['JAN','FEB',...,'DEC']，需要时我需要替换月份.

Concretely, I have a calendar of sorts, ['JAN','FEB',...,'DEC'] and I need to replace months as the need arises.

如果不移动，如何在Excel工作簿中订购工作表?您可以在指定工作表的之后或 之前插入工作表吗?

How do you order the sheets in an Excel workbook if you don't move them? Can you insert a sheet after or before a specified sheet?

只有另外一个我可以在SO上找到的帖子使用了win32com和Book.Worksheets.Add(After=Sheet);似乎很奇怪，这些模块都没有这种方法.

Only one other post I can find on SO uses win32com and Book.Worksheets.Add(After=Sheet); seems strange none of these modules would have this method.

默认似乎在工作簿的末尾添加了工作表.我可以复制目标文件，直到到达更新的工作表，插入新工作表，然后继续原始复制到末尾. (受的启发)

Default seems to add sheet at end of workbook. I could copy the destination file, until the updated sheet is reached, insert new sheet, and continue original copy to the end. (inspired by this post)

推荐答案

我遇到了两个问题.第一个问题是在给定位置插入一张纸.第二个问题是到处移动一张纸.由于我主要处理较新的Excel文件xlsx，因此我将使用openpyxl.

I had two problems. The first problem was inserting a sheet at a given position. The second problem was moving a sheet around. Since I mostly deal with the newer Excel file xlsx, then I would be using openpyxl.

各种来源表明新的工作表已添加到末尾.我希望每次都需要这样做，然后再移动工作表.我问了一个问题""((如何)移动工作表..." ，认为这样做可以解决这两个问题.

Various sources indicate new sheets are added to the end. I expected I would need to do this each time, and then move the sheet. I asked the question "(How to) move a worksheet..." thinking this was would solve both problems.

最终，第一个问题很容易，一旦我终于找到一个示例，该示例显示workbook.create_sheet()方法采用可选的index参数在给定的零索引位置插入新工作表. (我真的必须学习查看代码，因为答案在这里):

Ultimately, the first problem was easy once I finally found an example which showed workbook.create_sheet() method takes an optional index argument to insert a new sheet at a given zero-indexed position. (I really have to learn to look at the code, because the answer was here):

 def create_sheet(self, title=None, index=None):
        """Create a worksheet (at an optional index)
        [...]

下一步.原来，您可以通过重新排序工作簿容器_sheets来移动工作表.因此，我制作了一个辅助函数来测试该想法:

Next. Turns out you can move a sheet by reordering the Workbook container _sheets. So I made a little helper func to test the idea:

def neworder(shlist, tpos = 3):
    """Takes a list of ints, and inserts the last int, to tpos location (0-index)"""
    lst = []
    lpos = (len(shlist) - 1)
    print("Before:", [x for x in range(len(shlist))])
    # Just a counter
    for x in range(len(shlist)):
        if x > (tpos - 1) and x != tpos:
            lst.append(x-1)
        elif x == tpos:
            lst.append(lpos)
        else:
            lst.append(x)

    return lst

# Get the sheets in workbook
currentorder = wb.sheetnames
# move the last sheet to location `tpos`
myorder = neworder(currentorder)

>>>Before: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17]
>>>After : [0, 1, 2, 17, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]

# get each object instance from  wb._sheets, and replace
wb._sheets = [wb._sheets[i] for i in myorder]

一旦意识到它的作用，在openpyxl文档中不难发现第一个答案.令我感到有些惊讶的是，更多博客都没有提到移动工作表.

The first answer was not hard to spot in the openpyxl documentation once I realized what it did. Just a bit surprised more blogs didn't mention moving sheets around.
