tabled | use library for pretty print tables | Grid library

I'm using a Vue Bootstrap Table component and I want to add different CSS classes to different columns. I want my first column to have text-left, all the others text-center and the last one (right end one) to have text-right. Here is the current version of the b-table;

I try to create a delete method but it doesn't work, I use json-server with reactive forms, my description of the problem is quite simple because what I ask is quite simple I'm a junior trying to figure out how it all works.

i have an error : ERROR TypeError: product is undefined

ts.file

I'm trying to use https://datatables.net/

Currently we load all the table data in advance and do paging on the client side, which is obviously a bad idea, however I was not able to find a good example of how paging can be done on the server side.

Clearly, I should use ajax option but the documentation is very poor, see https://datatables.net/reference/option/ajax

It says the syntax is as follows:

I am loading JSON data from backend asp.net core c# API to ANGULAR material table but the problem is that the whole 100 JSON rows data load to the first page I have set up the paginator like below:

I am a newbie to angular I am trying to use paginator on a table but all the rows are being shown together and the pagination option is not working. I am not sure what I am doing wrong please guide me. Should I add mat-table tag for it or is normal table tag enough for this to work. I am literally new to this and dont know what more information I can give you

I'm trying to save data into a sqlite db, i have looked around but the strucutre for the helper is always this, i can't find out what's the problem. I don't get any exception, just is impossible write data into the db

I am using Material-Table in React and trying to increase the width of this 'lookup' column in 'Requirement' field. I have tried cellStyle: {columnWidth: 800}. Also, tried width, padding. None seem to accomplish this. I've checked through the documentation, and a few other places, but not able to resolve this. Appreciate anyone who knows how to make this change.

I just implemented SQLite database in my project, the app worked perfectly in the old app but after I transfer database files to another app and try to run it, It gave me this error

The app has:

• ListView listing player names from a DB table (only one column, so it is primary key)
• EditText to write the new name
• Button to update the name of player in the list

*there are more things, but i don´t want to make it more messy

I can click a name from the list and write a new name in the EditText. When you press the button that name is updated in the list.

Everything works correctly, but there is a problem. When I write a name that it is already in the list the app fails because primary keys cannot be repeated.

Is there some way to say "if EditText text already exists in the DB... then show a toast"

I already tried "if result of db.update is -1...then show a toast", but it doesn´t work.

This is the method in MainActivity:
