main_layout.addLayout(right_layout)

这段代码是将right_layout添加到main_layout中。在Qt中，可以使用QHBoxLayout或QVBoxLayout来创建布局，然后将它们添加到另一个布局中。这样可以通过嵌套来实现复杂的布局。在这个例子中，right_layout被添加到main_layout中，可能是作为右侧的布局。

你可以使用QPushButton的setStyleSheet方法设置按钮的样式表，将文本旋转90度，例如：

self.submit_btn.setStyleSheet('color: #fff; background-color: #20639b; border: none; font-size: 24px; padding: 10px; border-radius: 5px; transform: rotate(90deg);')

这里使用了transform属性将文本旋转了90度。

你可以在数据展示页面添加一个QLineEdit和一个QPushButton，让用户输入员工ID并点击按钮进行筛选。

具体实现方法如下：

1. 在QueryResultWindow类的初始化函数中添加以下代码来创建QLineEdit和QPushButton：

self.id_line_edit = QLineEdit()
self.filter_button = QPushButton('筛选')
self.filter_button.clicked.connect(self.filter_result)

2. 在layout中添加这两个控件：

layout.addWidget(self.id_line_edit)
layout.addWidget(self.filter_button)

3. 添加filter_result函数来执行筛选操作：

def filter_result(self):
    id = self.id_line_edit.text().strip()
    if len(id) == 0:
        QMessageBox.warning(self, '提示', '请输入员工ID')
        return
    db = pymysql.connect(host='39.99.214.172', user='root', password='Solotion.123', db='jj_tset')
    cursor = db.cursor()
    db_sql = f"SELECT * FROM table_name WHERE id = '{id}'"
    cursor.execute(db_sql)
    result = cursor.fetchall()
    db.close()
    if len(result) == 0:
        QMessageBox.information(self, "提示", "没有找到符合条件的记录")
        return
    self.table_widget.setRowCount(0)
    for row_num, row_data in enumerate(result):
        self.table_widget.insertRow(row_num)
        for col_num, col_data in enumerate(row_data):
            self.table_widget.setItem(row_num, col_num, QTableWidgetItem(str(col_data)))

注意替换db_sql中的table_name为你的表名。这个函数会从数据库中查询符合条件的记录并展示在表格中。

4. 修改show_query1_result函数，在最开始添加以下代码，用于展示所有记录：

db = pymysql.connect(host='39.99.214.172', user='root', password='Solotion.123', db='jj_tset')
cursor = db.cursor()
db_sql = """SELECT * FROM table_name"""
cursor.execute(db_sql)
result = cursor.fetchall()
db.close()
if len(result) == 0:
    QMessageBox.information(self, "提示", "今日无员工工资记录")
    return

注意同样替换db_sql中的table_name为你的表名。这个代码块会在进入数据展示页面时展示所有记录。

通过以上修改，你就可以在数据展示页面添加筛选功能了。
