icons and some buttons of spreadjs is not working

in this image paste button,find button and some of the default buttons are not working
is there anything with the package that need to change, or which package is it for icons
What you are describing is not the default behavior of SpreadJS's Designer Component ribbon. This sounds like an issue with how you are implementing the Designer Component.
I see here you tagged Vue.js so since this, I would recommend going through our documentation on getting started with the Designer Component with the Vue Framework and or our Designer Component Introduction blog.
I also wanted to note that we also have a Vue sample that uses SpreadJS and the Designer component available in our release download link (\SpreadJS.Release.xxxx\Designer\Designer Component\samples). You can download the latest release files from here.
If you have any other questions regarding using SpreadJS with the Designer Component, please reach out to the SpreadJS team by submitting a ticket.

How to extend the Image plugin in ckeditor5 with custom elements?

We're evaluating an upgrade from ckeditor 4 to the new ckeditor 5, but I need to be able to extend the Image plugin/package with some custom elements, e.g. a text input for licensing information about the image, a button/checkbox for toggling the image to be a thumbnail or not etc.
How can I add these custom elements in the image package and write my own javascript code to handle the values from these elements?
The image toolbar is being controlled by the config.image.toolbar property. It accepts names of UI components registered in the editor.ui.components factory. In other words, it works like the main editor toolbar which is configurable via editor.toolbar and you can learn more how to create buttons here: Creating a simple plugin.

How to utilize Angular 4 components when creating Leaflet Extended Control?

I am working now a few weeks with Leaflet and Angular CLI on a project involving geo map and in-door maps (Leaflet custom maps).
The application is conceptually very simple. I have to provide the user with a list of in-door locations (e.g. room) in a form of a simple location tree table, where, on user click, a new in-door map must be called. Also, I have to make a custom search box with a few filtering options for searching through sets of structured data and plotting the data on the maps in a form of Leaflet markers.
The question I have is the following: What would be the best way to implement the 2 above mentioned controls (location tree and search box), taking into account the nature of the app and the technology I am working with (Leaflet library and Angular CLI (angular 4.x))?
From my point of view, I can see 2 options by now:
1) Create the controls (location tree and search box with filters) using Leaflet L.control.extended (negative(-): seems to me that I have to statically type html in the L.control.extended 'onAdd' function in order to create the controls -> no possible Angular 4 templating engine advantages)
2) Create the controls using Angular 4 Component's templates, in Angular 4 fashion, neglecting the very existence of Leaflet L.control.extended (negative: It seems to me that this option unnecessary complicates the app + intuitively seems wrong since Leaflet extended control seems 'as born' for such types of problems)
It would be great if I could dynamically nest Angular component inside Leaflet custom control somehow. Any suggestions?

How to add filter row widget in rally tree grid

I have a rally tree grid. I want a filter widget just above the tree grid.
How we can add internal filter rally tree grid.
PFA screenshot.filter widget
Thanks.
There is an example in the docs:
2.0 will give you the black popover style one: https://help.rallydev.com/apps/2.0/doc/#!/example/filterable-grid-board
2.1 will give you the newer advanced filter:
https://help.rallydev.com/apps/2.1/doc/#!/example/filterable-grid-board
Both examples show using it with a board, but it should be straightforward to combine your existing code with the grid board component in the example- you just specify a gridConfig rather than a boardConfig.

Dojo Grid Template

In asp.net the DataGrid supports templates. You can provide your own template and have the grid fill the data in your template.
With Dojo Grid, it seems like I can't make my own template outside of the the rigid simplistic cell style grid that Dojo provides.
Does anyone know a way to use a custom template with Dojo Grid? Specifically, with Dojo you're forced to use a cell that corresponds to a data item. I'm looking to use a table as a template with any styling that I choose (rows,columns,rowspans,colspans, more than one data items in a single cell, etc).
Any clues please?
Thanks
Firstly, it sounds like everything you want is available by customizing the grid. You can do nesting of cells and even have things like Filtering Selects in rows. Unfortunately the docs on this are not awesome so it takes Googling and trial and error if you want very customized features.
Secondly, because of the OO nature of Dojo you can always use inheritance to create mixes of various widgets. Specifically the _templated class allows you to specify an HTML template for your widget, which themselves can included templated widgets.
If that sounds non-trivial, you're right, which is why I would suggest digging deeper into the Enhanced grid and probably open up the code before trying to write something yourself.
I can tell you that I struggled getting it working correctly, but I have hence been pleasantly surprised by features that I needed that I thought I would need to build myself but were built into the grid.
