宣言
for his nose was as sharp as
a pen, and <sic>a Table</sic> of green fields.

If all that is desired is to call attention to the apparent problem in the copy text, sic may be used alone:

I don't know, Juan. It's so far in the past now
— how <sic>we can</sic> prove or disprove anyone's theories?

It is also possible, using the choice and corr elements, to provide a corrected reading:

I don't know, Juan. It's so far in the past now
— how <choice>
 <sic>we can</sic>
 <corr>can we</corr>
</choice> prove or disprove anyone's theories?
for his nose was as sharp as
a pen, and <choice>
 <sic>a Table</sic>
 <corr>a' babbld</corr>
</choice> of green fields.
