Question

我的网页接收包含数组，对象数组和字符串的json数据。例如：

public static System.Drawing.Bitmap PadImage(System.Drawing.Bitmap originalImage)
        {
            if (originalImage.Height > 500)
             ??    
            if (originalImage.Width > 500)   
             ??

            Size squareSize = new Size(500, 500);
            System.Drawing.Bitmap squareImage = new System.Drawing.Bitmap(squareSize.Width, squareSize.Height);
            using (Graphics graphics = Graphics.FromImage(squareImage))
            {
                graphics.FillRectangle(System.Drawing.Brushes.White, 0, 0, squareSize.Width, squareSize.Height);
                graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;
                graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
                graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;

                graphics.DrawImage(originalImage, (squareSize.Width / 2) - (originalImage.Width / 2), (squareSize.Height / 2) - (originalImage.Height / 2), originalImage.Width, originalImage.Height);
            }
            return squareImage;
        }

我可以绘制一个表格，将每个对象属性显示为对应于对象数组中对象的行的单元格。

但是，根据data.staff [key] .active的值，我希望行具有特定颜色，最后一个单元格具有按钮或接收值。最后，我还可以绘制表格，其中表格主体中的每个元素都有一个自定义属性，其值也是从返回的json对象数组的键属性中获取的

使用rowCallBack。

 img = File.expand_path(Rails.root+'app/assets/images/scb_footer_logo.png')
 sheet.add_image(:image_src => img) do |image|
     image.start_at 6,6
     image.end_at 6,6
 end

DataTables行内容依赖于JSON数据
