      • calculateTargetWidth

        private float calculateTargetWidth​(Tag tag,
                                   float[] columnWidths,
                                   float outerWidth,
                                   WorkerContext ctx)
                            throws NoCustomContextException
        Calculates the target width. First checks:
        1. if the attribute or style "width" is found in the given tag and it is not wider than pageWidth - outerWidth, then the targetWidth = width value
        2. if the columnWidths array in total is not wider than pageWidth - outerWidth, then the targetWidth = the total of the columnWidths array
        3. if table's parent is a root tag or table has no parent, then the targetWidth = width of the page - outerWidth getTableOuterWidth(Tag, float, WorkerContext).
        If none of the above is true, the width of the table is set to its default with the columnWidths array.
        Parameters:
        tag - containing attributes and css.
        columnWidths - float[] containing the widest lines of text found in the columns.
        outerWidth - width needed for margins and borders.
        ctx -
        Returns:
        float the target width of a table.
        Throws:
        NoCustomContextException

        Adds horizontal border spacing to the right padding of the last cell of each row.
        Parameters:
        tableRows - List of TableRowElement objects of the table.
        horBorderSpacing - float containing the horizontal border spacing of the table.

      • setStyleValues

        public static TableStyleValues setStyleValues​(Tag tag)
        Set the table style values in a TableStyleValues object based on attributes and css of the given tag.

      • getBorderOrCellSpacing

        public static float getBorderOrCellSpacing​(boolean getHor,
                                           java.util.Map<java.lang.String,​java.lang.String> css,

        Extracts and parses the style border-spacing or the attribute cellspacing of a table tag, if present. Favors the style border-spacing over the attribute cellspacing.
        If style="border-collapse:collapse" is found in the css, the spacing is always 0f.
        If no spacing is set, the default of 1.5pt is returned.
        Parameters:
        getHor - true for horizontal spacing, false for vertical spacing.
        css - of the table tag.
        attributes - of the table tag.
        Returns:
        horizontal or vertical spacing between two cells or a cell and the border of the table.

      • setCellWidthAndWidestWord

        private float[] setCellWidthAndWidestWord​(HtmlCell cell)
        Sets the default cell width and widest word of a cell. These 2 widths are used as the starting point when determining the width of the table in
        Parameters:
        cell - HtmlCell of which the widths are needed.
        Returns:
        float array containing the default cell width and the widest word.
        • float[0] = cell width.
        • float[1] = widest word.

      • calculateDivWidestElementWidth

        private float calculateDivWidestElementWidth​(java.util.ArrayList<Element> divContent)
        An attempt to calculate a valid div width in case it is not fixed. It is used as alternative to div.getActualWidth, which doesn't work here in case of not fixed div's width (it returns 0). This method is probably has to be improved in future. The main idea of this method is to return the widest element's width, so the created cell will be able to contain it.
