我希望有一个最初没有行的表，然后动态创建每一行并能够删除每一行。
我得到了无法读取未定义的属性“childNodes”
请告诉我应该怎么做，
谢谢你。
function addRow() {
var table = document.getElementById("myTable");
var row = table.insertRow(0);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
}
function deleteRow(tableID) {
try {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for (var i = 0; i < rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
table.deleteRow(i);
rowCount--;
i--;
}
} catch (e) {
alert(e);
}

要删除所有行，只需从表中删除 html
function deleteRow(tableID) {
let table = document.getElementById(tableID)
table.innerHTML = "";
}
