Vamos a decir que el rango MyRange tiene:
<table border="1" bordercolor="#C0C0C0" bordercolordark="#FFFFFF" cellspacing="0" > <tr valign="top"> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>a</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>1</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>10</nobr></font></td> </tr> <tr valign="top"> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>b</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>2</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>20</nobr></font></td> </tr> <tr valign="top"> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>c</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>3</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>30</nobr></font></td> </tr> <tr valign="top"> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>d</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>4</nobr></font></td> <td width="63" height="21" align="center" valign="bottom"><font face="Monospace" size="1"><nobr>40</nobr></font></td> </tr></table>
Usando la forma sencilla de Index() faltando un argumento se puede sacar algo para una sola column:<ul>[*]Sacando columna 2<ul>[*]=SUM(INDEX(MyRange,,2)) = 10[*]=AVERAGE(INDEX(MyRange,,2)) = 2.5[/list][*]Usando columns 3<ul>[*]=SUM(INDEX(MyRange,,3))= 100[*]=AVERAGE(INDEX(MyRange,,3))= 25[/list][/list]Pero usando OFFSET se puede sacar dos columns (contiguas)
<ul>[*]=SUM(OFFSET(INDEX(MyRange,,2),0,0,,2))= 110[*]=AVERAGE(OFFSET(INDEX(MyRange,,2),0,0,,2))= 13.75[/list]
