pyqt5 qtablewdiget分别打印每列数据

# 导入必要的模块
from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem

# 创建一个QTableWidget对象
tableWidget = QTableWidget()

# 假设表格有3行和4列数据
rows = 3
columns = 4

# 设置表格的行数和列数
tableWidget.setRowCount(rows)
tableWidget.setColumnCount(columns)

# 填充表格数据（示例数据）
data = [
    ['A', 'B', 'C', 'D'],
    ['1', '2', '3', '4'],
    ['X', 'Y', 'Z', 'W']
]

for row in range(rows):
    for col in range(columns):
        item = QTableWidgetItem(data[row][col])
        tableWidget.setItem(row, col, item)

# 打印每列数据
for col in range(columns):
    column_data = []
    for row in range(rows):
        item = tableWidget.item(row, col)
        column_data.append(item.text())
    print(f"Column {col+1} data: {column_data}")
