Hello Dale,

From your post, my understanding on this issue is: you want to know how to
dynamically resize the Named Range when new rows are appended to it and how
to adjust the named range below the table. If I'm off base, please feel
free to let me know.

For the first question, Named range will be adjusted automatically if the
Insert (row) method is called on cells within it. Suppose we get the Range
object of the last row and call its 'Insert' method, we may find that the
new row is automatically added into the named range:
Excel.Range lastRow = (Excel.Range)name.RefersToRange.Rows[rows.Count,
missing];
lastRow.Insert(Excel.XlDirection.xlDown, true);
But unfortunately, Excel does not support inserting a row below the caller
(such as the 'lastRow' in the above code). The new blank row appears before
the 'lastRow'. A possible workaround is to temporarily make the original
named range include an extra row beneath the last data row, then call
Insert on this extra row. When the datasets are imported, we remove the row
from the named range.

As FSt1 suggested, another method is to adjust the named range every time
when a new row or cell is added by calling NamedRange.RefersToR1C1 = <new
range.

For the second question, the named ranges below the table will be shifted
automatically by Excel when new rows are added to the table.

Please let me know if you have any other concerns, or need anything else.

Sincerely,
Jialiang Ge , remove 'online.')
