Without having the source Markdown to work with it’s a bit of guesswork, but going off your screenshot, but it looks like a (a) table with an (b) ![[embedded note]] containing a (c) list.
You could try some combination of these (adjusting the values as desired) to see if the spacing looks any better for you.
/* all embeds - padding (top-right-bottom-left) */
.markdown-embed {
padding: 0 0 0 10px;
}
/* rendered list indentation */
.markdown-rendered ul, .markdown-rendered ol {
padding-inline-start: 1.2em;
}
/* rendered list indentation in tables only */
.markdown-rendered th :is(ul, ol) {
padding-inline-start: 1.2em;
}
