Yii complex table?

Question

Yii

Can you please tell me how to implement the following?

About TbGroupGridView in the know. So I can group by recipient

But how to bring the footer to the center, and more than one?
Or spit and make a few grids? Who has any thoughts?
---
As far as I understand, 'extraRowColumns'=> array('firstLetter') should also be used?
---
upd
despite the fact that they say here that any table can be implemented on yii mona, I think it might be worth using the same https://www.datatables.net/examples/advanced_init/... instead of the standard grid. how do you like this decision?

Answer 1

Maybe this extension will work demos.krajee.com/grid-demo

Answer 2

1) Look at the code of TbGroupGridView and TbTotalSumColumn, its developer had exactly the same task as you. He successfully solved it. In his code is a solution ready for you. You just have to compose and change a little.
2) It is much more productive, which is relevant for large amounts of data, not to use the extension, but to display the data as you need using conventional means. echo '';
3) I advise you to use not server power, but a client for drawing (with the same ReactJS it will turn out very beautiful, extensible and compact).
