This is a classic use case for XSLT 2.0's for-each-group instruction.

Are you using 2.0?

If so, an approach like

<xsl:for-each-group select="note/node()" group-adjacent="if
(self::table) then 'table' else 'interstitial'">

    <xsl:choose>
        <xsl:when test="current-grouping-key() eq 'table'">
            <!-- do what you do to tables -->
        </xsl:when>
        <xsl:when test="current-grouping-key() eq 'interstial'>
            <!-- wrap everything else -->
        <xsl:otherwise>
            <!-- you should never get here; die loudly -->
        </xsl:otherwise>
    </xsl:choose>

</xsl:for-each-group>

ought to work.  (The pattern also extends.)

If you have to individual wrap adjacent tables you may want a different
grouping attribute, and you might want to select
note/node()[normalize-space()] instead, to avoid white-space only text
nodes.
