Change look a TDBGRID to make it more modern

Hi, I'm using TMS Unicode for Delphi 7 but the TTntDBGrid looks quite old and ugly. I want to make it look more "modern" and I think that the solution would to make a parent class or hook in runtime or other ways. I have to stick to Delphi 7 as cannot move to a newer version of Delphi (with UNICODE support) 1) In the attached image, you have on the left the TntDBGrid style and on the right another grid from a third party component. Would it be possible to make TntDBGrid to look more like the image on the right? 2) Also, when I click on the TntDBGrid column, you an see a ugly black line (which appears when resizing column is possible). I want to get rid of that black line and make possible resizing the columns. 3) The sort arrow indicators on the column header does not appear on TntDBGrid. I will like that arrow too. Summing up, I would like the 3 above tasks. I have the TNT Unicode source code in case that you need it for changing the original source code. Or if you think of other solution like runtime hooking the component, etc. I'm happy with that too. Just let me know. Thanks!
