Table headers position:sticky and border issue
You can add
.table {
border-collapse: separate;
}
But unfortunately it looks bad, a better solution will be adding a workaround using a pseudo-element.
th:after,
th:before {
content: '';
position: absolute;
left: 0;
width: 100%;
}
th:before {
top: -1px;
border-top: 1px solid red;
}
th:after {
bottom: -1px;
border-bottom: 2px solid red;
}
.table-sticky-container {
height: 200px;
overflow-y: scroll;
border-top: 1px solid green;
border-bottom: 1px solid green;
}
.table-sticky th {
position: -webkit-sticky;
position: sticky;
top: 0;
z-index: 2;
}
th:after,
th:before {
content: '';
position: absolute;
left: 0;
width: 100%;
}
th:before {
top: -1px;
border-top: 1px solid red;
}
th:after {
bottom: -1px;
border-bottom: 2px solid red;
}

The second solution
.table {
border-collapse: collapse;
}
.table-sticky thead th {
position: -webkit-sticky;
position: sticky;
top: 0;
z-index: 2;
box-shadow: inset 0 1px 0 red, inset 0 -2px 0 red;
}
You can add
.table {
border-collapse: separate;
border-spacing: 0;
}
