[lzzhanglin]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

i add css like this: .ant-table table{border-collapse: separete;} .ant-table-thead > tr:first-child > th:last-child{border-top-right-radius:4px;}

What does the proposed API look like?

in border separate mode,the apperance of table too ugly.in border collapse mode,the corner of table has blank area
