Hướng dẫn how do you append rows in excel? - làm cách nào để bạn nối các hàng trong excel?

An append operation creates a new query that contains all rows from a first query followed by all rows from a second query. The append operation requires at least two queries. These queries can also be based on different external data sources.

The append operation is based on the names of the column headers in both tables, and not their relative column position. The final table has all matching columns from all tables appended. If the tables don’t have matching columns, null values are added to the unmatched column. The tables will be appended in the order in which they're selected, starting with the Primary table. 

You can perform two types of append operations. With an inline append, you append data to your existing query until you reach a final result. The result is a new step at the end of the current query. With an intermediate append, you create a new query for each append operation. 

Security Note:  Privacy Levels prevent a user from inadvertently combining data from multiple data sources, which may be private or organizational. Depending on the query, a user could inadvertently send data from the private data source to another data source that might be malicious. Power Query analyzes each data source and classifies it into the defined level of privacy: Public, Organizational, and Private. For more information, see Set privacy levels [Power Query].

1. To open a query, locate one previously loaded from the Power Query Editor, select a cell in the data, and then select Query > Edit. For more information see Create, load, or edit a query in Excel.

2. Select Home > Append Queries. The default action is to do an inline append. To do an intermediate append, select the arrow next to the command, and then select Append Queries as New.

   The Append dialog box appears.

3. Decide the number of tables you want to append:

   • Select Two tables, and then select the second table in the drop down list box to append.

   • Select Three or more tables. From the Available tables box, add the tables you want to append to the Tables to append. Use the arrows on the right of that box to change sequence.

4. Select OK.OK.

Result

• If you chose to do an inline append in step 2, a new step in the current query is created. You can continue adding steps to the same query to append additional queries.

• If you chose to do an intermediate append in step 2, a new query is created. You can continue creating additional queries.
