ElementUI table closes extended row cannot select row change

Table rendering successfully selects a row and renders the currently selected row
. El-table__body tr.current-row > td {
background-color:-sharp1d8ce0;te;
}
while the user expands a row of expand, the current expanded row is also given the color
.el-table__body tr.expanded > td {
background-color:-sharp1d8ce0;
color: white;.
}
but when the user closes the expanded row, the row click cannot be selected again, and it will be selected only if another row is selected and then clicked again
