我正在尝试使用AlivePdf在我的flex应用程序上创建一个pdf表：

奇怪的是脚本创建了一个带双头的表，我不知道为什么。您可以在此链接中看到生成的pdf：https://docs.google.com/viewer?url=prestitiinpdap.biz/pdf/myPDF.pdf

Answer 1

您使用的是哪个版本的库？我试图用当前版本0.1.5RC编译你的代码，编译器找不到一些类。

修正类路径后，我发现“new Grid（...）”构造函数需要7个参数（在你的情况下只有4个）。

另一个问题是“网格（...）”中的“宽度”。我不知道，开发商想用它来表达什么。我只能用60来获得普通视图。

毕竟我有以下PDF：

尝试一下，可能会对你有帮助。

Answer 2

使用网格创建PDF时，我遇到了重复标题的问题，如此处所述。这是你问题发生后的几年，但自从我现在遇到它，这是我的解决方案......

为了确保使用最新的AlivePDF版本，我从他们的SVN下载了最新的源代码：http://alivepdf.googlecode.com/svn/trunk/AlivePDFBeta/src

我认为它是作为AlivePDF 0.1.5 RC发布的，但是分布式SWC似乎在某些方法签名上存在差异。

在扫描AlivePDF源代码以了解与添加Grid标头相关的行为时，我注意到了类 org.alivepdf.pdf.PDF ，公共方法 addGrid 。这种方法确实错误地添加了Grid标头 2次。通过将 4178 行注释到 4180 来修复此问题，如以下源代码所示。

包含注释部分的完整方法：

public function addGrid ( grid:Grid, x:Number=0, y:Number=0, repeatHeader:Boolean=true ):void
        {   
            if ( textColor == null ) 
                throw new Error("Please call the setFont and textStyle method before adding a Grid.");

            currentGrid = grid;
            currentGrid.x = x;
            currentGrid.y = y;
            var i:int = 0;
            var j:int = 0;

            currentGrid.generateColumns(false);
            columns = currentGrid.columns;

            var row:Array;
            columnNames = new Array();
            var lngColumns:int = columns.length;    
            var item:*;

            for (i = 0; i< lngColumns; i++)
                columnNames.push ( new GridCell(columns[i].headerText, currentGrid.headerColor ) );

            var rect:Rectangle = getRect ( columnNames, currentGrid.headerHeight );
            if ( checkPageBreak(rect.height) )
                addPage();

            // Commented to avoid the duplicate header issue:
            //setXY (x +currentGrid.x, y+getY() );
            //addRow( columnNames,'', rect);
            //endFill();

            setXY ( x+getX(), y+getY() );
            addRow( columnNames, GridRowType.HEADER, rect );

            if (grid.cells == null)
                grid.generateCells();

            var buffer:Array = grid.cells;
            var lngRows:int = buffer.length;

            for (i = 0; i< lngRows; i++)
            {

                item = buffer[i];
                row = new Array();
                for (j = 0; j< lngColumns; j++)
                {
                    row.push (item[columns[j].dataField] != null ? item[columns[j].dataField] : "");
                    nb = Math.min(nb,nbLines(columns[j].width,row[j]));
                }

                row = buffer[i];


                rect = getRect ( row, currentGrid.rowHeight );
                setX ( x + getX());

                if ( checkPageBreak(rect.height) )
                {
                    addPage();
                    setXY ( x+getX(),nextPageY );
                    //setXY ( x+getX(),y+getY() ); hacked to allow user to set the next Page Y of Grid
                    if ( repeatHeader ) 
                    {
                        addRow (columnNames, GridRowType.HEADER, getRect(columnNames, currentGrid.headerHeight) ); // header
                        setX ( x + getX() );
                    }
                }

                if ( grid.useAlternativeRowColor && Boolean(isEven = i&1) )
                    addRow( row, GridRowType.ALTERNATIVE, rect );
                else addRow( row, GridRowType.NORMAL, rect );
            }
        }

为什么Alivepdf生成双表头？
