recently there has been a bit of a trick in working on a table generator.
when you click on a new column, a new column is added to the title and a new column is added to all the content. Click to add a new line. The new line is the same as the title. Here is my layout and js code.
layout
</script>
question, where is my js contaminated.
you can copy the above code and execute it directly.
if it"s something else, please explain to me
