    * </a>
    * <p>
    * Indeed, the code as presented by the OP does not show the header table. This makes sense, though:
    * </p>
    * <p>
    * The OP has cells with default padding (i.e. 2) and height 10, and he tries to insert text at height 7.
    * But 2 (top margin) + 7 (text height) + 2 (bottom margin) = 11, i.e. more than fits into the cell height 10.
    * Thus, the text does not fit and is not displayed.
    * </p>
    * <p>
    * You can fix this by either
    * <ul>
    * <li>using a smaller font, e.g. 6, or
    * <li>using a higher cell, e.g. 11, or
