I'm using a QAbstractTableModel to edit a panda dataframe. Editing the contents of the table was easy but i can't find the way to rename columns and rows inplace(like the rest of the data in the table). How I can do that?

Is there a way to filter table columns data as there is a way in excel to filter.
Filtering manually require a very long code if data is huge. So trying to find an easy way. Please suggest something.
I went through the following link for the same but need an easier and efficient approach.

There's no built-in filter capability for TableViews like Excel.
I've written a library that provides the GUI filters, but you'll still need to programmatically apply the results to filter your dataset:

https://github.com/jhsheets/javafx-filterable-table-columns
I wrote an extension for that use case:

The implementation of the filter is quite easy. You wrap your TableView with the TableFilter and add the columns that should be filterd by tableFilter.filterColumn(TableColumn column)
1 Build your TableView like usual by code or fxml
TableView<Pojo> table = new TableView<>();
table.getItems().addAll(pojoList);
TableColumn<Pojo, String> columnA = new TableColumn<>("ColA");
TableColumn<Pojo, String> columnB = new TableColumn<>("ColB");
table.getColumns().add(columnA);
table.getColumns().add(columnB);
2 After that apply the filter
TableFilter<Pojo> tableFilter = new TableFilter<>(table);
tableFilter.filterColumn(columnA);
tableFilter.filterColumn(columnB);
I have three tables. One table is referred as two tables. How to display the table in the following manner.
Thanks in advance.
You can place components in table so you can create columns which contains tables. The down side is the inside table will be duplicated each row (with headers for each table). Perhaps the vaadin 7.4 Grid will make a better job here.
Please read the docs for this feature:

How to display the details in Gridview by using existing table data, suppose i have 3
tables .i.e Tables_Name: Studentdetails, Class, Section.
I want to display StudentId,StudentName,ClassName,Section in another table gridview,
Your datasource will need to be based on some query that joins the data from those three tables (can they be joined?), from there you just populate the gridview with the resulting dataset. It's hard to give any more of a detailed answer without more detail I'm afraid.
I have this UITableView (http://imgur.com/3YQzm) that I want to list 3 textfields on each row. The info is stored on a SQLite d/b. The first row I need for titles.
How can I list the info in each row so it looks "nice" (i.e. lined up in columns)? Do I need a custom cell for this?
As far I know, you have to put the labels in the specific locations, so you have to define the coordenates for a nice look. I don't know if you are using a xib file for the cell, but, for this case, is better to use it. In the xib will be easy to set the correct location for your labels.
Using QTableView I would like to be able to select multiple cells and change all selected cells at once. How I can do it?
I'm not sure exactly what you mean by "changing" the selected cells (content, formatting, something else?) but I think QTableView::selectedIndexes() (or QTableView::selectionModel() if you need more power) is going to help out. You can loop through the returned indexes and update your underlying model.
If you are using a QSortFilterProxyModel you will have to use the QSortFilterProxyModel::mapFromSource() and related methods to map from the selected cells on your table view to the actual model indexes.
