Problem Description:

We can drag the fill handle of the selection frame in spreadsheet to fill adjacent cells automatically. But it doesn't support the data that contains number and text, like "item 1", or "1st period"

Reproducing Steps:

1. display the attached excel file in spreadsheet
2. select and drag 2 cells with "item 1" and "item 2" (or drag "1st period") to fill adjacent cells
2. use fill handle to fill adjacent cells, but it only copies cells' value.

expected:
adjacent cells should be filled with ""item 3"", ""item 4"" (increasing number)
or
"2nd period" , "3rd period"

actual:
just fill duplicated value.
