QTextCursor insertText不起作用

Question

我正在尝试使用QTextTable在QT中创建一个表。我设置背景和文本时第一行工作正常，但第二行仅应用格式化，但insertText函数似乎对我不起作用。我也尝试过insertHTML，但在第2行似乎没什么用。

QTextTableFormat channelBankFormat;
channelBankFormat.setAlignment(Qt::AlignHCenter);
//channelBankFormat.setHeight(8);
channelBankFormat.setColumnWidthConstraints(constraints);
channelBankFormat.setBorder(0);

ChannelBank->clear();
QTextCursor cursor = ChannelBank->textCursor();
cursor.beginEditBlock();

QTextTable *table = cursor.insertTable(2, 5, channelBankFormat);
QTextCharFormat headerFormat = cursor.charFormat();
headerFormat.setFontWeight(QFont::Bold);
headerFormat.setFontPointSize(8);

QTextCharFormat dataFormat = cursor.charFormat();
dataFormat.setFontPointSize(12);

QTextBlockFormat centerAlignment;
centerAlignment.setAlignment(Qt::AlignCenter);

for (int cellNumber = 1; cellNumber <= 5; ++cellNumber) {
    QTextTableCell  cell                = table->cellAt(0, cellNumber-1);
    QTextCharFormat headerCellFormat    = cell.format();
    QTextCursor     cellCursor          = cell.firstCursorPosition();

    headerCellFormat.setBackground(QColor(0 + (cellNumber * 50), 222, 222, 127));
    cell.setFormat(headerCellFormat);
    cellCursor.clearSelection();
    cellCursor.insertText("---",headerFormat);
}
for (int cellNumber = 1; cellNumber <= 5; ++cellNumber) {
    QTextTableCell  cell                = table->cellAt(1, cellNumber-1);
    QTextCharFormat headerCellFormat    = cell.format();
    QTextCursor     cellCursor          = cell.lastCursorPosition();

    headerCellFormat.setBackground(QColor(0 + (cellNumber * 50), 222, 222, 127));
    cell.setFormat(headerCellFormat);
    cellCursor.clearSelection();
    cellCursor.insertText("---",headerFormat);
}
cursor.endEditBlock();

找到了罪魁祸首：     channelBankFormat.setHeight（8）;
