create table with no lines

It is possible.

Which theme have you?
There’s some CSS in style.css line 1359 that is applying borders to your table headings and table data;

.art-article th, .art-article td {
 ...
 border: solid 1px #8099B3;
 ...
}

To override this adding of borders and if your theme is not custom built, you should use either a Child Theme or Custom CSS plugin. If you edit the theme’s original files, your changes will be lost if you update the theme.

Within your Child Theme stylesheet, or Custom CSS plugin’s allocated area, try adding;

.art-article th, .art-article td {
 border: none;
}
