Concatenate two tables along the rows by merging columns.
The total number of rows will be the sum of the two tables. The total number of columns will depend if the two table
have common columns (based on name).
If the two table have the same column (based on name), the values of theses columns are concatenated (starting from the first table) into the same column.
If a column doesn't exist in the other table, it will be concatenate with value provided in the Fill empty values with parameter.
Example
Let's say you have the following tables.
Here is the result of the row concatenation.
| A |
B |
C |
| A1 |
B1 |
NaN |
| A2 |
B2 |
NaN |
| A3 |
NaN |
C3 |
| A4 |
NaN |
C4 |
NaN value are create for the B and C columns because they don't exist in the other table. You can provide another value with the Fill empty values with parameter.
The first two rows will have the tags from the first table and the last two rows will have the tags from the second.
The column tags will depend on Column tags options parameter.
Parameters
Column tags options
This parameter allows you to define what to do with the column tags. Here is the different options:
ignore: the tags are ignored and left emptykeep first: only the tags of the first table are keeptmerge from first table: tags of the first and second table are merged (the first table tags override the second table tags)
