可以在最后一列添加当日总工资汇总，你可以在添加数据到表格的循环中，计算当日总工资并将其添加到最后一列中，类似这样：

# 添加数据到表格
for row_num, row_data in enumerate(result):
    self.query1_window.table_widget.insertRow(row_num)
    total_salary = row_data[-1] # 获取当前行的当日总工资
    for col_num, col_data in enumerate(row_data):
        if col_num == len(row_data)-1:
            self.query1_window.table_widget.setItem(row_num, col_num, QTableWidgetItem(str(total_salary))) # 将当日总工资添加到最后一列
        else:
            self.query1_window.table_widget.setItem(row_num, col_num, QTableWidgetItem(str(col_data)))

这里假设当日总工资是结果集中的最后一列。如果不是，你需要修改代码中的 `len(row_data)-1` 为对应的列索引。

你可以通过以下方式更改表格列名：

1. 在创建表格时设置列名：

   self.table_widget.setColumnCount(3)
   self.table_widget.setHorizontalHeaderLabels(['姓名', '年龄', '性别'])

2. 在查询数据之前，先清空表格并设置列名：

   self.table_widget.setRowCount(0)
   self.table_widget.setColumnCount(3)
   self.table_widget.setHorizontalHeaderLabels(['姓名', '年龄', '性别'])

然后再将查询结果添加到表格中。

self.query1_window = QueryResultWindow() self.query2_window = QueryResultWindow() def show_query1_result(self): # 查询数据 db = pymysql.connect(host='39.99.214.172', user='root', password='Solotion.123', db='jj_tset') cursor = db.cursor() db_sql = """ """ cursor.execute(db_sql) result = cursor.fetchall() db.close() # 清空表格 self.query1_window.table_widget.setRowCount(0) self.query1_window.table_widget.setColumnCount(len(result[0])) # 添加数据到表格 for row_num, row_data in enumerate(result): self.query1_window.table_widget.insertRow(row_num) for col_num, col_data in enumerate(row_data): self.query1_window.table_widget.setItem(row_num, col_num, QTableWidgetItem(str(col_data))) # 显示窗口 self.query1_window.show()这里怎么更改表格列名

你可以在表格创建后，使用setHorizontalHeaderLabels方法来设置表格的列名。例如：

self.query1_window.table_widget.setColumnCount(len(result[0]))
self.query1_window.table_widget.setHorizontalHeaderLabels(["列1", "列2", "列3"])

其中，["列1", "列2", "列3"]是你要设置的列名列表。你可以根据你的需求修改它。
