您可以通过实现QAbstractTableModel的data()函数来设置单元格的字体颜色。在该函数中,您可以检查其他单元格的值,并根据需要设置当前单元格的字体颜色。以下是一个示例实现:
```python
from PyQt5.QtGui import QColor, QFont
from PyQt5.QtCore import Qt, QAbstractTableModel
class MyTableModel(QAbstractTableModel):
def __init__(self, data, headers):
QAbstractTableModel.__init__(self)
self._data = data
self._headers = headers
def rowCount(self, parent):
return len(self._data)
def columnCount(self, parent):
return len(self._data[0])
def data(self, index, role):
if role == Qt.DisplayRole:
return self._data[index.row()][index.column()]
elif role == Qt.FontRole:
# Check other cells and set font accordingly
font = QFont()
# Example: if value in column 0 is greater than 5, set font to bold
if index.column() != 0:
if self._data[index.row()][0] > 5:
font.setBold(True)
return font
elif role == Qt.TextAlignmentRole:
return Qt.AlignCenter
elif role == Qt.BackgroundRole:
return QColor(Qt.white)
elif role == Qt.ForegroundRole:
# Check other cells and set color accordingly
color = QColor(Qt.black)
# Example: if value in column 1 is less than 0, set color to red
if index.column() != 1:
if self._data[index.row()][1] < 0:
color = QColor(Qt.red)
return color
else:
return None
def headerData(self, section, orientation, role):
if role == Qt.DisplayRole:
if orientation == Qt.Horizontal:
return self._headers[section]
else:
return "Row %d" % section
else:
return None
```
在上述示例中,我们实现了data()函数来设置单元格的字体和颜色。我们检查其他单元格的值,并根据需要设置当前单元格的字体和颜色。在本例中,我们检查第一列的值是否大于5,如果是,则将字体设置为粗体。我们还检查第二列的值是否小于0,如果是,则将字体颜色设置为红色。您可以根据需要修改此示例以满足您的需求。
