It’s quite simple, there is an attribute for this (you need to search for documentation to see everything that exists in each element) although it is recommended not to use it anymore. I will use an example that uses the attribute to follow the style you are using, but your HTML is well outside of what is used today. tags as <center>
should not be used either, the use of <iframe>
which should also be avoided seems to be being misused as well. Another problem is that something tells me that you are using the tag to compose layout when it was made only to create tables as its name says.
<table border=0>
Documentation of <table>
.
Note that it can be obtained more appropriately with CSS:
#tabela {
border: 0px;
margin: 0px auto;
width: 500px;
height: 600px;
}
<table id="tabela">
<tr>
<td>
texto1
</td>
</tr>
<tr>
<td>
texto2
</td>
</tr>
</table>
I put in the Github for future reference.

I reversed your edit because you completely changed the question. Post a separate question about how to affect only the desired elements with CSS.

do you want me to ask a new question? Or continue with this?

Make a new one. Or do a search for the basics of CSS.
