使用 PyQt6 并排添加带有 Pixmap 的 QTableWidget 和 QLabel

Question

我正在尝试在 python 中使用 PyQt6 构建一个 GUI，在选项卡右侧创建一个表格和一个图像。

由于某种原因，它创建了占据整个屏幕的表格并且不显示 QLabel（现在我使用文本作为占位符）。

def set_tab_info(self, num_rows): # Sets the structure for each tab
    self.num_rows = num_rows
    tab_info = [

        tab_layout = QGridLayout(tab_widget)
        
        horizontal_layout = QGridLayout()
        
        table = QTableWidget(self.num_rows, info["columns"])
        table.setHorizontalHeaderLabels(info["header_labels"])
        
        for row in range(self.num_rows):
            for col in range(info["columns"]):
                if info["editor_types"][col] == "line_edit":
                    item = QLineEdit()
                    table.setCellWidget(row, col, item)
                    self.column_inputs[(info["name"], info["header_labels"][col])] = item
                elif info["editor_types"][col] == "combo_box":
                    item = QComboBox()
                    item.addItems(self.get_combo_box_items(info["header_labels"][col]))
                    table.setCellWidget(row, col, item)
                    self.column_inputs[(info["name"], info["header_labels"][col])] = item
                else:
                    item = QTableWidgetItem()
                    
                table.setItem(row, col, QTableWidgetItem())
                
        table.resizeColumnsToContents()
            
        image_label = QLabel("Placeholder")
        horizontal_layout.addWidget(table, 0, 0, 1, 2)
        horizontal_layout.addWidget(image_label, 0, 1, 1, 1)
        
        tab_layout.addLayout(horizontal_layout, 1, 0, 1, 3)
        self.tabs.addTab(table, info["name"])

我做了一些研究，并尝试向 ChatGPT 寻求帮助，但我无法找到它不显示 QLabel 的任何原因。在下面找到它现在的样子的图片。

如果可能的话，我希望表格水平占据屏幕的 2/3，图像占据剩余的 1/3

        self.set_tab_info(num_rows)
