+ \brief The QConcatenateTablesProxyModel class proxies multiple source models, concatenating their rows
+
+ \ingroup model-view
+
+ QConcatenateTablesProxyModel takes multiple source models and concatenates their rows.
+
+ In other words, the proxy will have all rows of the first source model,
+ followed by all rows of the second source model, and so on.
+
+ If the source models don't have the same number of columns, the proxy will only
+ have as many columns as the source model with the smallest number of columns.
+ Additional columns in other source models will simply be ignored.
+
+ Source models can be added and removed at runtime, and the column count is adjusted accordingly.
+
+ This proxy does not inherit from QAbstractProxyModel because it uses multiple source
+ models, rather than a single one.
+
+ Only flat models (lists and tables) are supported, tree models are not.
