我需要帮助上色我QTableView中。 @rainer帮我把颜色，当我初始化表，但现在，我已经有数据（但没有颜色//我的数据是在我的桌子开了CSV）的表，我想创建，当点击它的按钮颜色的tableview在某些行中，当存在与-2（数据）的行，这将是与颜色蓝色像.. - 我有一个按钮和一个表格。 此按钮CSV数据加载到我的tableview。 我想有一个新的按钮，该颜色该表中的行。 （但只颜色具有数据的-2，例如行）有些代码：
self.fileName = (_fromUtf8('tweets.csv'))
self.tableView = QTableView(self.tabSentimento)
self.tableView.setGeometry(QRect(550,10,510,700))
self.tableView.setObjectName(_fromUtf8("TabelaSentimento"))
self.tableView.setModel(self.model)
self.tableView.horizontalHeader().setStretchLastSection(True)
self.pushButtonLoad = QPushButton(self.tabSentimento)
self.pushButtonLoad.setGeometry(QRect(550,720,130,30))
self.pushButtonLoad.setObjectName(_fromUtf8("buttonLoadCSV"))
self.pushButtonLoad.setText(QApplication.translate("Form", "Process!", None, QApplication.UnicodeUTF8))
self.pushButtonLoad.setStyleSheet('color:red;background-color:rgb(255, 255, 153);border:1px solid purple;')
self.pushButtonLoad.clicked.connect(self.on_pushButtonLoad_clicked)
def loadCsv(self, fileName):
with open(fileName, "rb") as fileInput:
for row in csv.reader(fileInput):
items = [
QStandardItem(field)
for field in row
]
self.model.appendRow(items)
def on_pushButtonLoad_clicked(self):
print self.fileName
self.loadCsv(self.fileName)
例如，您可以继承模型，并重新实现data方法，该代码示例将单元格背景颜色变为蓝色，如果pushButtonColorize检查和单元格的值等于1，这也将影响细胞同排。
