pandas 更改不同工作表的列顏色

Question

我有一個腳本可以讀取多個 excel 文件並將它們作為表格放入最終的 excel 中。

我還有一個 function 為工作簿中的所有工作表填充藍色的列名背景，但我希望某些列的顏色為綠色，而其他特定工作表的顏色為藍色，可以這樣做嗎？

這是我的腳本：

def gitanalysis():
    dest = createdir()
    dfGitUsers = pd.read_excel(os.path.join(dest, "GitUsers.xlsx"))
    dfGitUsers.fillna("N/A", inplace=True)
    dfGitGroupMembership = pd.read_excel(os.path.join(dest, "GitGroupMembership.xlsx"))
    dfGitRepoGroupAccess= pd.read_excel(os.path.join(dest,"GitRepoGroupAccess.xlsx"))
    dfGitReposSize=pd.read_excel(os.path.join(dest,"GitReposSize.xlsx"))
    dfGitRepoLastChangeDate=pd.read_excel(os.path.join(dest,"GitRepoLastChangeDate.xlsx"))
    pathdest = path_dir()

    # below its the path from where reads "CM_UserDetails.xlsx" file to add it in the excel sheet
    dfUserDetails = pd.read_excel(rf"{pathdest}\CM_UsersDetails.xlsx")
    dfUserDetails.fillna("N/A", inplace=True)

    timestr = time.strftime("%Y-%m-%d-")
    xlwriter = pd.ExcelWriter(os.path.join(dest, f'{timestr}Usage-GitAnalysis.xlsx'))
    dfUserDetails.to_excel(xlwriter, sheet_name='UserDetails', index=False)
    dfGitUsers.to_excel(xlwriter, sheet_name='GitUsers', index=False)
    dfGitGroupMembership.to_excel(xlwriter, sheet_name='GitGroupMembership', index=False)
    dfGitRepoGroupAccess.to_excel(xlwriter,sheet_name='GitRepoGroupAccess',index=False)
    dfGitReposSize.to_excel(xlwriter,sheet_name='GitReposSize',index=False)
    dfGitRepoLastChangeDate.to_excel(xlwriter,sheet_name='GitRepoLastChangeDate',index=False)
    for column in dfGitUsers:
        column_width = max(dfGitUsers[column].astype(str).map(len).max(), len(column))
        col_idx = dfGitUsers.columns.get_loc(column)
        xlwriter.sheets['GitUsers'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['UserDetails'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitGroupMembership'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitRepoGroupAccess'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitReposSize'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitRepoLastChangeDate'].set_column(col_idx,col_idx,column_width)

#THIS IS WHERE I CHANGE THE BG Color to Blue

    workbook = xlwriter.book
    cell_format = workbook.add_format({'bg_color': 'blue'})
    cell_format.set_bold()
    cell_format.set_font_color('black')
    cell_format.set_border(1)

    for sheet_name in xlwriter.sheets:
        ws = xlwriter.sheets[sheet_name]
        ws.freeze_panes(1, 0)
        ws.conditional_format('A1:{}1'.format(chr(65 + ws.dim_colmax)), {'type': 'no_blanks', 'format': cell_format})

    xlwriter.close()
    print("GitSvnAnalysis.xlsx was exported with succes!")

這是它的外觀：

這是此表的預期 output：

IIUC ，對於您的所有工作表，您希望前兩列為綠色，其他列為 header 行的藍色。

您可以嘗試使用以下代碼為 header 行着色，其中代碼#92D050對應於color green ， #00B0F0對應於light blue 。

def gitanalysis():
    dest = createdir()
    dfGitUsers = pd.read_excel(os.path.join(dest, "GitUsers.xlsx"))
    dfGitUsers.fillna("N/A", inplace=True)
    dfGitGroupMembership = pd.read_excel(os.path.join(dest, "GitGroupMembership.xlsx"))
    dfGitRepoGroupAccess= pd.read_excel(os.path.join(dest,"GitRepoGroupAccess.xlsx"))
    dfGitReposSize=pd.read_excel(os.path.join(dest,"GitReposSize.xlsx"))
    dfGitRepoLastChangeDate=pd.read_excel(os.path.join(dest,"GitRepoLastChangeDate.xlsx"))
    pathdest = path_dir()

    # below its the path from where reads "CM_UserDetails.xlsx" file to add it in the excel sheet
    dfUserDetails = pd.read_excel(rf"{pathdest}\CM_UsersDetails.xlsx")
    dfUserDetails.fillna("N/A", inplace=True)

    timestr = time.strftime("%Y-%m-%d-")
    xlwriter = pd.ExcelWriter(os.path.join(dest, f'{timestr}Usage-GitAnalysis.xlsx'))
    dfUserDetails.to_excel(xlwriter, sheet_name='UserDetails', index=False)
    dfGitUsers.to_excel(xlwriter, sheet_name='GitUsers', index=False)
    dfGitGroupMembership.to_excel(xlwriter, sheet_name='GitGroupMembership', index=False)
    dfGitRepoGroupAccess.to_excel(xlwriter,sheet_name='GitRepoGroupAccess',index=False)
    dfGitReposSize.to_excel(xlwriter,sheet_name='GitReposSize',index=False)
    dfGitRepoLastChangeDate.to_excel(xlwriter,sheet_name='GitRepoLastChangeDate',index=False)
    for column in dfGitUsers:
        column_width = max(dfGitUsers[column].astype(str).map(len).max(), len(column))
        col_idx = dfGitUsers.columns.get_loc(column)
        xlwriter.sheets['GitUsers'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['UserDetails'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitGroupMembership'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitRepoGroupAccess'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitReposSize'].set_column(col_idx, col_idx, column_width)
        xlwriter.sheets['GitRepoLastChangeDate'].set_column(col_idx,col_idx,column_width)


    workbook = xlwriter.book
    # Green color for the first two cells
    cell_format_green = workbook.add_format({'bg_color': '#92D050'})
    cell_format_green.set_bold()
    cell_format_green.set_font_color('black')
    cell_format_green.set_border(1)
    # Blue color for the next cells
    cell_format_blue = workbook.add_format({'bg_color': '#00B0F0'})
    cell_format_blue.set_bold()
    cell_format_blue.set_font_color('black')
    cell_format_blue.set_border(1)

    for sheet_name in xlwriter.sheets:
        ws = xlwriter.sheets[sheet_name]
        ws.freeze_panes(1, 0)
        ws.conditional_format('A1:B1', {'type': 'no_blanks', 'format': cell_format_green})
        ws.conditional_format('C1:{}1'.format(chr(65 + ws.dim_colmax)), {'type': 'no_blanks', 'format': cell_format_blue})

    xlwriter.close()
    print("GitSvnAnalysis.xlsx was exported with success!")

Output：

這給了我們預期的 output
