Add spaces in the AE specific tables when drill down from the baseline characteristic table

[LittleBeannie]

The AE-specific table typically includes some spacing before the rows labeled "with one or more adverse events," "with no adverse events," and the AE terms.

While, in the current AE specific table, which is drill down from the baseline characteristic table, there is no space. One possible way of adding this space is adding "\u2003\u2003" before these rows.

One potential solution for adding this space is to insert "\u2003\u2003" before these rows.
