推荐答案

它并不复杂：它仅限于绘图，然后首先设置一个面板（或类似的）绘制并处理它的Paint事件。



然后编写一个采用DataRow和Graphics上下文以及Y偏移量的方法。对DataTable中的每一行重复调用它。



在方法内部，您需要为行中的每个单元格创建RectangleF对象，然后调用 Graphics.DrawText [ ^ ]，将RectangleF和单元格内容作为字符串传递给它。试试看：对于固定的表格报告来说，这真的不是那么复杂 - 如果你需要灵活处理细胞数量，大小和位置，或者只是变得复杂文本换行/省略号生成。

It's not complex: It you are limited to Drawing only, then first set up a Panel (or similar) to draw onto, and handle its Paint event.

Then write a method that takes a DataRow and a Graphics context, and a Y offset. Call it repeatedly for each row in the DataTable.

Inside the method you need to create RectangleF objects for each cell in the row and just call Graphics.DrawText[^], passing it the RectangleF and the cell contents as a string.

Try it: It's really not that complex for a "fixed" table report - it only gets complex if you need to be flexible with the cell count, sizes and location, or text wrapping / ellipsis generation.
