    Default QTextTableCell border 1pt bottom append.

    How i can subclass QTextTableCell to paint only border bottom 1pt black solid? ( or only left , top .... )
    ist this possibel ?

    I suppose to append after on HTML QTextDocument tohtml td style
    border-bottom:1px solid black;

    Qt Code: 
    1. void  Fop_Handler::ParserTable( const QDomElement e , QTextDocument * d , Fop_Layer * layer , int CursorPositon ) 
    2. {
    3.  
    4.     if (FoTag(e) != TABLE_TAG) {

    7.  
    8.     Fop_Block *foppi = new Fop_Block(imagecounter,e,"fo:table");    /* grep current source to play */
    9.     qreal tableborderborder = TakeOneBorder(e);
    10.     qreal tablewidth = Unit(e.attribute ("width",QString("0")));
    11.     QDomElement co = e.parentNode().toElement();
    12.     QTextCursor Tcursor = QTextCursor(d);
    13.     bool IsCorrectCursor = Tcursor.movePosition(QTextCursor::End);
    14.     int mappos = Tcursor.position();  /* last position from last cursor on class ! */
    15.  
    16.   QTextCursor cellCursor;  /* new cursor only for cell tabbing */
    17.   QString tatype = e.attribute( "table-layout" );  /* on attribute root table */
    18.   QStringList coolsizes;  /* grep  column size in pt cm mm ecc... */
    19.   coolsizes.clear();
    20.   QDomElement bodytable = e.firstChildElement("fo:table-body");
    21.   int rowCounter = 0;
    22.   int columnCounter = 0;
    23.     QDomElement column = e.firstChildElement("fo:table-column"); 
    24.     while (!column.isNull()) {

    26.            if (sizefromcool.size() > 0) {
