iview table用jquery合并单元格问题

iview table合并单元格问题

因为我只需要合并第一列如有contentsid相同合并
mounted() {
let tds = $("#myList tbody tr").find(“td:first”);
this.mergeTable(tds);
tds = $("#allList tbody tr").find(“td:first”);
this.mergeTable(tds);
}

mergeTable(tds) {
let curr = $(tds[0]);
let idx = 0;
for (let i = idx; i < tds.length; i++) {
if (
curr.find(“span”).text() ==
$(tds[i])
.find(“span”)
.text()
) {
idx++;
if (idx != 1) {
$(tds[i]).remove();
}
} else {
curr.attr(“rowspan”, idx);
idx = 1;
curr = $(tds[i]);
}
}
}
