Concatenating Data Tables
Example of Concatenating Data Tables
Suppose you want to concatenate two data tables—Trial1 and Trial2—into a new data table. Select
Tables > Concatenate, add the opened data tables you want to concatenate as shown in Figure 7.23,
and then click OK.

7 Reshaping Data
The data tables combine into a new untitled table with all rows from the first data table followed by all
rows from the second data table, as shown in Figure 7.24.

Concatenated data tables always have a column for every column name found in the original data
tables. In Figure 7.24, there are two columns that do not match between the data tables: yield1 and
yield2, so the new concatenated data table shown has both yield1 and yield2 columns. These columns
have missing values for rows from the data table in which the column did not exist.
