Purpose With AppendRow you can add a row to a table variable and copy the content of the structured variable to the new row.
Example AppendRow V[customerinfo] table=V[customers]

A new empty row ist appended to the table variable V[customers]. For each component of the structure  V[customerinfo] for which a table column with same name exists the component content is copied to the corresponding table cell.

Format AppendRow V[strname] table=V[tabname]  

The structured variable and the table may have a different structure. Table columns without a matching counterpart in the structure remain empty.
