Code for dynamically deleting rows and columns of Table based on JQuery_jquery

First, I need to get the number of rows in the Table. I add the table through the background, so when I get it in the front desk, I get the total number of assignments by length
For example, in the picture above:
If I want to print this table but don’t want to operate it What to do with the contents of that column?

Copy code The code is as follows:

for(var i=0;i{
　$("table tr").eq(i).find("td").eq(0).remove();
}

Explanation:
Num is the list sum obtained from the background. 1 is also removed for the header.
The first eq(i) is to get the TR index in the Table
The second eq(0) is to get the first TD position in the TR
