public java.lang.StringgetAlignment()

        return _alignment;
protected abstract java.lang.StringgetCellValue(org.apache.struts2.components.table.WebTable table, java.lang.Object data, int row, int col)
this is the method that subclasses need to implement to set their value. they should not override renderCell unless they want to change the alignmnent renderering

protected booleanisAligned()
        return _alignment != null;
    
public java.lang.StringrenderCell(org.apache.struts2.components.table.WebTable table, java.lang.Object data, int row, int col)
implememnts CellRenderer renderCell. It sets the alignment. gets the actual
data from getCellValue
        if (isAligned()) {
            StringBuffer buf = new StringBuffer(256);
            buf.append("<div align='").append(_alignment).append("'>");
            buf.append(getCellValue(table, data, row, col));
            buf.append("</div>");

            return buf.toString();
        }

        return getCellValue(table, data, row, col);
