33<h2>Description</h2>
34
35<p>The widget concatenates multiple sets of examples. The merge is "vertical", in
36a sense that two sets of 10 and 5 examples yield a new set of 15 examples.</p>

40<p>In case one of the tables is connected to the widget as the primary table, the
41resulting table will contain these same attributes. If there is no primary table,
42the attributes can be either a union of all attributes that appear in the tables
43specified as "Additional Tables", or their intersection, that is, a list of attributes
44which appear in all the connected tables.</p>

47<h2>Example</h2>

49<p>The widget can be used, for instance, for merging the data coming from three
50separate files, as shown below.</p>
