[GUI Develop] DBGrid-mutiple-head DL : 0: 轻松实现DBGrid多表头加强版网上流传的TADBgrid控件可以轻松实现DBGrid多表头，不过它的设计较简单，相邻字段，层数必须相同才可以合并，这样效果就大打折扣了，我本来给他 90分的，就这一点就扣了89分。我下功夫改了一下，即使层数也可以合并，还做到最底层的高度尽量小，效果与DBGridEh几乎一样，因为比较简单，没有解决折行，这需要在内存做一棵树来计算高度，复杂些，可参考DBGridEH, 下面就是实现的代码，如果发现有错，请指出改正。-easily DBGrid strengthen multi-table first version TADBgrid spread of the Internet can easily control it now DBGrid multi-table heads, but its design is relatively simple, adjacent fields, the same rise can be merged, this effect will be greatly reduced, I would have to give him 90 points, on this point deduction of 89 points. I make efforts to reform it, and even floors also can be combined, but also achieve a high degree of the bottom as possible, effects DBGridEh almost the same as it is more simple, no address lines, This needs to do in memory to calculate a tree height, more complex, reference DBGridEH. Below is the realization of the code, if found to be wrong, please correct that.
