Method Detail

### addTableEvent

    public void addTableEvent(PdfPTableEvent event)

  Add a page event to the forwarder.

  Parameters:
    `event` - an event that has to be added to the forwarder.

### tableLayout

    public void tableLayout(PdfPTable table,
                            float[][] widths,
                            float[] heights,
                            int headerRows,
                            int rowStart,
                            PdfContentByte[] canvases)

  Description copied from interface: `PdfPTableEvent`
  This method is called at the end of the table rendering. The text or graphics are added to one of the 4 `PdfContentByte` contained in `canvases`.
  The indexes to `canvases` are:

  - `PdfPTable.BASECANVAS` - the original `PdfContentByte`. Anything placed here will be under the table.
  - `PdfPTable.BACKGROUNDCANVAS` - the layer where the background goes to.
  - `PdfPTable.LINECANVAS` - the layer where the lines go to.
  - `PdfPTable.TEXTCANVAS` - the layer where the text go to. Anything placed here will be over the table.
  The layers are placed in sequence on top of each other.

  The `widths` and `heights` have the coordinates of the cells.
  The size of the `widths` array is the number of rows. Each sub-array in `widths` corresponds to the x column border positions where the first element is the x coordinate of the left table border and the last element is the x coordinate of the right table border. If colspan is not used all the sub-arrays in `widths` are the same.
  For the `heights` the first element is the y coordinate of the top table border and the last element is the y coordinate of the bottom table border.

  Specified by:
    `tableLayout` in interface `PdfPTableEvent`
  Parameters:
    `table` - the `PdfPTable` in use
    `widths` - an array of arrays with the cells' x positions. It has the length of the number of rows
    `heights` - an array with the cells' y positions. It has a length of the number of rows + 1
    `headerRows` - the number of rows defined for the header.
    `rowStart` - the first row number after the header
    `canvases` - an array of `PdfContentByte`
