OpenPyXL 中的列和行维度总是 None

Question

为什么 openpyxl 将每一行和每一列维度读取为 None？无论 table 是通过 openpyxl 还是在 Microsoft Excel.

中创建的，都是这种情况

import openpyxl
wb = openpyxl.load_workbook(r'C:\data\MyTable.xlsx')
ws = wb.active
print ws.row_dimensions[1].height
print ws.column_dimensions['A'].width

打印 None 和 None。这些没有隐藏 columns/rows。在 Excel.

中查看时，它们显然具有尺寸

我知道用迭代器加载工作簿会阻止创建维度字典，但这会导致键错误，我在这里不使用迭代器。

是否有其他方法来确定 cell/row/column 的 width/height？

===============解决方案=================

感谢 Charlie，我意识到以下是获取所有行高列表的最佳方法：

import openpyxl
wb = openpyxl.load_workbook(r'C:\Data\Test.xlsx')
ws = wb.active
rowHeights = [ws.row_dimensions[i+1].height for i in range(ws.max_row)]
rowHeights = [15 if rh is None else rh for rh in rowHeights]

Answer 1

RowDimension 和 ColumnDimension 对象仅在要覆盖默认值时才存在。所以 ws.row_dimensions[1].height 将永远是 None 直到它被赋值。

默认值为：{'defaultRowHeight': '15', 'baseColWidth': '10'}

Answer 2

openpyxl: 3.0.4

源代码：from openpyxl.worksheet.dimensions import SheetFormatProperties

显示 {'defaultRowHeight': 15, 'baseColWidth': 8}

# dimensions.py

class SheetFormatProperties(Serialisable):

    ...

    def __init__(self,
                 baseColWidth=8,  # <-----------------
                 defaultColWidth=None,
                 defaultRowHeight=15,  # <------------
                 customHeight=None,
                 zeroHeight=None,
                 thickTop=None,
                 thickBottom=None,
                 outlineLevelRow=None,
                 outlineLevelCol=None,
                ):
        self.baseColWidth = baseColWidth
        self.defaultColWidth = defaultColWidth
        self.defaultRowHeight = defaultRowHeight
        self.customHeight = customHeight
        self.zeroHeight = zeroHeight
        ...

一个例子

from openpyxl import load_workbook
from openpyxl.worksheet.dimensions import SheetFormatProperties
from openpyxl.worksheet.worksheet import Worksheet

wb = load_workbook('xxx.xlsx')
for sheet in [wb[sheet_name] for sheet_name in wb.sheetnames]:
    sheet: Worksheet
    sheet_prop: SheetFormatProperties = sheet.sheet_format
    default_width = sheet_prop.baseColWidth
    default_height = sheet_prop.defaultRowHeight

OpenPyXL 中的列和行维度总是 None

Column and row dimensions in OpenPyXL are always None
