推荐答案

如果要在插入文本时进行对齐，可以使用alignment = Qt：AlignHCenter调用此函数。

If you want to do the alignment as you are inserting the text, you can call this function with alignment = Qt:AlignHCenter. You can modify the function to also specify the character formatting.

// Insert text with specified alignment in specified cell
void insertAlignedText(QTextTable *table, int row, int col, Qt::Alignment alignment, QString text)
{
    // Obtain cursor and current block format
    QTextCursor textCursor = table->cellAt(row,col).firstCursorPosition();
    QTextBlockFormat blockFormat = textCursor.blockFormat();

    // Read vertical part of current alignment flags
    Qt::Alignment vertAlign = blockFormat.alignment() & Qt::AlignVertical_Mask;

    // Mask out vertical part of specified alignment flags
    Qt::Alignment horzAlign = alignment & Qt::AlignHorizontal_Mask;

    // Combine current vertical and specified horizontal alignment
    Qt::Alignment combAlign = horzAlign | vertAlign;

    // Apply and write
    blockFormat.setAlignment(combAlign);
    textCursor.setBlockFormat(blockFormat);
    textCursor.insertText(text);
}
