本文探讨了如何从PDF文件中识别并提取表格数据的方法。作者希望通过使用矩形算法来定位表格的位置，并进一步解析表格的具体内容，包括表头、行和列等元素。
I want to recognize tables inside PDF, now I have rectangles of the PDF Text Object.I'm confused about how to implement this rectangle algorithm. The programming language what I use is VC++.
What I want to get is:
The Result is a perfect table with header, rows, columns.Can anyone help me? How to rectangle table from these rectangles? These rectangles' orginal point
(0, 0) is on the bottom-left point. x coordinate grow from left to right, and y coordinate grow from bottom to up.I don't want to use 3rd party. I want to implement this function through rectangle algorithm.
Any help would be greatly appreciated!
