1. qtablewidget增加选择框？

cb = QtWidgets.QTableWidgetItem()
# item 转为checkbox，样式受checkbox样式影响
cb.setFlags(QtCore.Qt.ItemIsUserCheckable | QtCore.Qt.ItemIsEnabled)
# 居中
cb.setTextAlignment(QtCore.Qt.AlignCenter)
# 选中状态
cb.setCheckState(QtCore.Qt.Unchecked if not row.checked else QtCore.Qt.Checked)
# i：第i行，0：第0列，
self._table_widget.setItem(i, 0, cb)

样式：

/*---------qcheckbox-----------*/
QCheckBox {
}

QCheckBox::indicator {
    /* 选择框尺寸 */
}

QCheckBox::indicator::checked:pressed {
    image:url(:/resource/checkbox-checked.png);
}
QCheckBox::indicator::checked {
    image:url(:/resource/checkbox-checked.png);
}

2. QTableWidget设置进度条QProgressBar

bar = QtWidgets.QProgressBar()
bar.setMinimum(0)
bar.setMaximum(100)
bar.setValue(100)
bar.setTextVisible(True)
self._table_widget.setCellWidget(0, 4, bar)

样式

QProgressBar {
    text-align: right;
    vertical-align: center;
    padding-right: 40px;
    color: $selectBackground;
}
