@EvertEt I wasn't able to see the issue, could you add more details please?

For sure @marianayap !

The issue is visible here: (the sandbox above)

Adding fixed: "right" to the last column:

@EvertEt I can see the issue when I add fixed: "right" but I still don't have very clear what should happen

should become

@EvertEt I can see the issue when I add fixed: "right" but I still don't have very clear what should happen

he just want the effect of the overflow table-right show like the fixed:right at the column header.i guess

Can I take it?

It looks like that the z-index of .ant-table-container::after is too small.

PR welcome!

@EvertEt Hello! it seems that if you add this line of code
{ title: 'Action', key: 'operation', fixed: 'right', width: 100, render: () => <a>action</a>, },

after { title: "Column 8", dataIndex: "address", key: "8" } in line 64 it works

Yes, that's indeed what is explained in the first message. The bug is visible when there is no fixed: right column

@EvertEt @marianayap The issue caused the ''sticky" property for Table. if you use it , the class 'ant-table-sticky-header' is added table header. The css as below:
.ant-table-sticky-header { position: -webkit-sticky; position: sticky; z-index: calc(2 + 1); }
why is 2+1? 'cause the siblings ant-table-body is 2.
@EvertEt the shadow you mentioned ,the css like this:
.ant-table-ping-right:not(.ant-table-has-fix-right) .ant-table-container::after { -webkit-box-shadow: inset -10px 0 8px -8px rgba(0, 0, 0, 0.15); box-shadow: inset -10px 0 8px -8px rgba(0, 0, 0, 0.15); }
if use default z-index ,the value is 1, so if you want to fix this ,try set z-index is bigger than 3 ,for example 4.
.ant-table-ping-right:not(.ant-table-has-fix-right) .ant-table-container::after { -webkit-box-shadow: inset -10px 0 8px -8px rgba(0, 0, 0, 0.15); box-shadow: inset -10px 0 8px -8px rgba(0, 0, 0, 0.15); z-index: 4; }

I think this bug can be fixed in react-components/table: https://github.com/react-component/table/tree/master/src

I will research more ,and PR will be pulled in next days.
