I don't see tbody rendering any rows. I copied code from live demo basic-example.

[SanthoshVeeramalla]

Installed using the command npm install -save ng-table-virtual-scroll.

My tbody does not have any rows displayed. I copied the code from live demo basic one and the data is also available from util.ts file.

Does it need a specific version of angular cdk and material, etc?

Also i do not see the below div after rendering:

My package.json shows the following: "@angular/cdk": "^7.2.1", "@angular/material": "^7.2.1", "ng-table-virtual-scroll": "^1.3.1",

Me neither, not rendering tbody. Does anyone know?

Same issue

[diprokon]

Can someone, please, provide example with the issue? I cannot reproduce the problem with provided package.json

@diprokon Can you share your working stackblitz version with "@angular/cdk": "^7.2.0", "@angular/material": "^7.2.0", "ng-table-virtual-scroll": "^1.3.1",

From what I see - The element cdk-virtual-scroll-viewport is created and then directly first child is a table. On the newer versions - I saw that there is a container after cdk-virtual-scroll-viewport. But it is missing on these versions.

I suppose it is the core of the issue.

[msqar]

i was able to make it work but it's suuuper laggy to render new items, is that normal? is that angular's fault? T__T

[victoriaunizhona]

@msqar Can you share your code or what was wrong and you have changed?

[AmbroiseVuaridel]

Same for me

[AmbroiseVuaridel]

i was missing import {ScrollingModule} from "@angular/cdk/scrolling"; it works well after adding it

[victoriaunizhona]

Adding import {ScrollingModule} from "@angular/cdk/scrolling"; helped. @diprokon Maybe you can consider adding that to the instructions?

Still as msqar mentioned - it is very laggy. Loading even slower than without virtual scroll.

[AudriusButkevicius]

So I tried the suggested steps here of including the scrolling module, and it didn't work, spent tons of time trying to figure out why.

It seems that on a live reload server when you include the scrolling module in your app module, the reload server only reloads the module file, it does not recompile or reload the component file, hence why it doesn't work.

I had to re-save the component file for it to be recompiled and reloaded properly, at which point stuff started working.

This didn't work for me either 😭
