PyQt的从Excel填充QTableWidget的

Question

我尝试填充QTableWidget的与Excel文件的一些数据，我想行添加到我的QTable只有ID即为listID，我在QTable细胞得不到数据

https://drive.google.com/file/d/0B_PFK3V2Ij4tSko4emplYmNuN1E/view?usp=sharing这里Excel文件，它不包含任何formatin或公式，只是空的行和列，因为automaticaly产生

文件这里是我的代码

wb = openpyxl.load_workbook(os.path.join(os.getcwd(), file), read_only=True) 
ws = wb.active 

headers = [] 
for item in ws[4]: 
    headers.append(item.value) 
headers.pop(0) 

listID = [] 
for index in range(self.listWidgetID.count()): 
    listID.append(self.listWidgetID.item(index).text()) 

data = ws.iter_rows(row_offset=5, column_offset=1) 

row_increment = 0 
self.tableWidgetDATA.setRowCount(1) 
self.tableWidgetDATA.setColumnCount(len(headers)) 
self.tableWidgetDATA.setHorizontalHeaderLabels(headers) 

for x, rows in enumerate(data): 
    if str(rows[0].value) in listID: 
     for y, cell in enumerate(rows): 
      item = QTableWidgetItem(str(cell.value)) 
      self.tableWidgetDATA.setItem(x, y, item) 
     row_increment = row_increment + 1 
     self.tableWidgetDATA.setRowCount(row_increment)

将元素添加到QTableWidget，该POSITI on必须是setRowCount()，在你的情况下，你在添加后更新，所以它不会被保存，另一个错误是你不验证数据是否有效。

class Widget(QWidget): 
    def __init__(self, parent=None): 
     QWidget.__init__(self, parent) 

     self.tableWidgetDATA = QTableWidget(self) 
     self.listWidgetID = QListWidget(self) 
     self.setLayout(QVBoxLayout()) 
     self.layout().addWidget(self.listWidgetID) 
     self.layout().addWidget(self.tableWidgetDATA) 
     self.listWidgetID.addItems(["113894", "113906", "113895"]) 
     file = "Livro2.xlsx" 
     wb = openpyxl.load_workbook(os.path.join(os.getcwd(), file), read_only=True) 
     ws = wb.active 

     headers = [item.value for item in ws[4] if item.value is not None] 

     listID = [self.listWidgetID.item(i).text() for i in range(self.listWidgetID.count())] 

     data = ws.iter_rows(row_offset=5, column_offset=1) 

     self.tableWidgetDATA.setColumnCount(len(headers)) 
     self.tableWidgetDATA.setHorizontalHeaderLabels(headers) 

     for x, rows in enumerate(data): 
      if rows[0].value is not None: 
       if str(rows[0].value) in listID: 
        self.tableWidgetDATA.setRowCount(self.tableWidgetDATA.rowCount()+1) 
        for y, cell in enumerate(rows): 
         val = cell.value 
         if val is not None: 
          item = QTableWidgetItem(str(val)) 
          self.tableWidgetDATA.setItem(self.tableWidgetDATA.rowCount()-1, y, item) 

输出：
