Python xlwt导出excel完整

发布时间:2019-07-24 09:53:46编辑:auto阅读(1560)

    有一组任务数据,要把它excel下载下来,如果仅仅导出,用csv导出就很方便。

    但是要导出漂亮的样式,重复的地方要合并单元格,设置背影颜色,字体,边框等。而CSV是纯文本格式,不支持设置各种样式。

    研究了一天,把代码写了出来。

    背影颜色参考地址,搜索_colour_map_text

    样式设置参考地址

    完整代码如下:

    
    import xlwt
    
    book = xlwt.Workbook(encoding='utf-8')
    sheet = book.add_sheet('sheetname')
    
    def set_style(color='white', height=260, bold=False):
    
        #: 设置单元格字体
        style = xlwt.XFStyle()
        font = xlwt.Font()
        # font.name = name
        font.bold = bold
        font.color_index = 4
        font.height = height
        style.font = font
    
        # 设置单元格背景颜色
        pattern = xlwt.Pattern()
        pattern.pattern = xlwt.Pattern.SOLID_PATTERN
        pattern.pattern_fore_colour = xlwt.Style.colour_map[color]
        style.pattern = pattern
    
        #:设置单元格边框线条
        borders = xlwt.Borders()  # Create Borders
        # May be: NO_LINE, THIN, MEDIUM, DASHED, DOTTED, THICK, DOUBLE, HAIR,
        # MEDIUM_DASHED, THIN_DASH_DOTTED, MEDIUM_DASH_DOTTED,
        # THIN_DASH_DOT_DOTTED, MEDIUM_DASH_DOT_DOTTED,
        # SLANTED_MEDIUM_DASH_DOTTED, or 0x00 through 0x0D.
        borders.left = xlwt.Borders.THIN
        borders.right = xlwt.Borders.THIN
        borders.top = xlwt.Borders.THIN
        borders.bottom = xlwt.Borders.THIN
        style.borders = borders  # Add Borders to Style
    
        #: 设置单元格居中格式
        alignment = xlwt.Alignment()  # Create Alignment
        # May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT, HORZ_FILLED,
        # HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED
        alignment.horz = xlwt.Alignment.HORZ_CENTER  # 横向居中
        alignment.vert = xlwt.Alignment.VERT_CENTER  # 纵向居中  May be: VERT_TOP, VERT_CENTER, VERT_BOTTOM, VERT_JUSTIFIED, VERT_DISTRIBUTED
        alignment.wrap = xlwt.Alignment.WRAP_AT_RIGHT  # :自动换行
        style.alignment = alignment
        return style
    
    #:模拟数据
