JQuery-based code for dynamically deleting rows and columns in a Table

First, you need to obtain the number of rows in the Table. I add tables in the background. So when I get the Table at the front end, I get the total number of values by length.
For example:
What should I do if I want to print the table but do not want to operate on the content of the column? Copy codeThe Code is as follows: for (var I = 0; I <num + 1; I ++)
{
$ ("Table tr"). eq (I). find ("td"). eq (0). remove ();
}

Explanation:
Num is the total list obtained from the background + 1 is to remove the header.
The first eq (I) is to obtain the TR index in the Table.
The second eq (0) is to obtain the first TD position in TR.
