How to change row height in QTextTable

I'm writing the complicated rich text editor, derived from QTextEdit class. It must be able to insert, resize, and apply various formatting to embedded tables.

I found function for setup column widths (setColumnWidthConstraints). But there is no one to change _rows_ heights.

Is there any way to achieve this?

Example code:

void CustomTextEdit::insertTable (int rows_cnt, int columns_cnt)
{
    QTextCursor cursor = textCursor ();
    QTextTableFormat table_format;
    table_format.setCellPadding (5);

    // TODO: This call just changed the frame border height, not table itself.
    //table_format.setHeight (50);

    // Setup columns widths - all is working perfectly.
    QVector <QTextLength> col_widths;
    for (int i = 0; i < columns_cnt; ++i)
        col_widths << QTextLength (QTextLength::PercentageLength, 100.0 / columns_cnt);
    table_format.setColumnWidthConstraints (col_widths);

    // ...But there is no similar function as setRowHeighConstraints for rows!

    // Insert our table with specified format settings
    cursor.insertTable (rows_cnt, columns_cnt, table_format);
}
