<column> (Index of Column Containing Unique Values for Record)

This element specifies the column within the specified external data source that contains unique data for the current record within that data source. This element shall be used in conjunction with the <uniqueTag> element (§2.14.35) to maintain a relationship between a specific record within an external data source and a given source or merged document. The @val attribute on this element shall be interpreted as a zero-based index into the columns specified by the data source, specifying the resulting column as the column in which the <uniqueTag> element shall be looked up.

If this element specifies a column number which exceeds the number of columns in the specified external data source, then its value shall be ignored.

Note: 
<w:recipientData>
  <w:active w:val="0" />
  <w:column w:val="12" /> 
  <w:uniqueTag w:val="258865469" /> 
</w:recipientData>

The external data record associated with this information is specified via the column in the external data source corresponding to the <column> element with a @val attribute equal to 12, which contains a row whose value in this column has a value corresponding to the <uniqueTag> element (§2.14.35) with a @val attribute equal to 258865469. This record will not be imported into the merged WordprocessingML document as the <active> (§2.14.1) element associated with the given external data record has a @val attribute equal to 0.

In other words, when the specified external data source is connected to, the record within the thirteenth column of the external data source that has the contents 258865469, and not populate mapped fields in a merged document with data from that record. ]
