如果比例尺的值是11：500，你只要输入500就行，1：1500就1500
在table实例化时显示默认是1行1列，且行高、列宽都是1，但是事实上行列数正确，但是行高、列宽却不是标称的1，而是行高4.6，列宽7.5，不知道是怎么回事！而且设置的值低于这两个数时，是无效的设置。比如设置mytable.setrowheight(2),那么行高仍然是4.6，是不能改变的，列宽也是同样的情况。
所以上述代码你的比例尺如果输入的是
请问各位高手这个问题怎么解决啊？
发觉是table本身问题，在cad中用表格工具画表格时也是一样的！看来是bug，和字体的大小有关系！ 我决定自己写个制作表格的类，用多段线画！到时候贴上来。郁闷阿！

table类是有点问题，不知道是autocad .net本身的问题，还是我们的编码有问题。
c#最适合开发autocad，因为它拥有vb容易的特点，却具有vc++的强大功能。
