python基礎處理excel合並單元格

一、讀寫單元格數據基礎方法了解

work_book = xlrd3.open_workbook("test_data.xls",formatting_info=True)  #讀取excel文件，創建工作薄對象

sheet = work_book.sheet_by_name("Sheet1") # 根據sheet名創建對應的表格對象

cell_value = sheet.cell_value(0,1) #獲取單元格的值

tuper = sheet.merged_cells  #獲取sheet中所有的合並單元格

nrowls = sheet.nrows 獲取行數

ncols = sheet.ncols 獲取列數

將處理單元格進行二次封裝

1-）定義一個類：
class ExcelUtils:
    def __init__(self,excel_file_path,sheet_name):
        self.excel_file_path = excel_file_path
        self.sheet_name = sheet_name
        # self.work_book = xlrd3.open_workbook(self.excel_file_path, formatting_info=True)
        self.work_book = xlrd3.open_workbook(self.excel_file_path)
        # self.sheet = self.get_sheet()
        self.sheet = self.work_book.sheet_by_name(self.sheet_name)

2-）處理合並單元格，讓合並單元格中每一個格子取出左上角的值

    def get_merged_cell_value(self,row_value, col_value):
        for (min_row_index, max_row_index, min_col_index, max_col_index) in self.sheet.merged_cells:
            if row_value >= min_row_index and row_value < max_row_index:
                if col_value >= min_col_index and col_value < max_col_index:
                    cell_value = self.sheet.cell_value(min_row_index, min_col_index)
                    break  #防止在第一次循環完成取出值后，再次循環判斷，覆蓋原本的值
                else:
                    cell_value = self.sheet.cell_value(row_value, col_value)
            else:
                cell_value = self.sheet.cell_value(row_value, col_value)
        return cell_value
