i'm trying to use Mat table from angular material, so the console shows an error as you see in this picture

core.js:10101 NG0303: Can't bind to 'matCellDefOf' since it isn't a known property of 'td'. enter image description here

and here's code

I'm trying to run my Flutter app on my phone, connected via USB, in order to debug.

It stopped working from one day (May 13, if it matters) to the next. Quite frustrating is that I made no changes since it last worked. Since the last time I clicked the Android Studio "play" button on May 13, there were only code changes, which all ran fine via hot reload. Then the next day when pressing the play button, it suddenly complains about JAVA_HOME not being set.

After some troubleshooting, I now get the error message

i am developing an application with laravel 8 and livewire. In a blade view of my application I need to insert a graph, and the graph is inserted inside the template I have chosen. In the template I have an example file that indicates how to populate the graph and called morris-init.js, then in vendor/morris I have the file morris.min.js. These two javascripts are called from my script and css configuration file dz.php. In my blade view, I have two livewire components, and in the second component I have a table (which is shown correctly) and the graph with the related script. My problem is that the graph is shown correctly, but not with the data passed by my script, it uses the data from the morris-init.js file. By deleting the morris-init.js file from the config file the graph is not being rendered in my livewire component. On the console I have noticed these errors (screenshot attached), but I cannot understand what the problem may be. Anyone have any suggestions or ideas on what the problem may be? Thank you all!

My code:

I am trying to create table on plugin activation, I tried making the same function inside the class and calling it from the constructor, and I tried calling it outside the class and finally i tried to make another php file for calling it using the register_activation_hook, but nothing worked

I have made a code in JavaScript to concatenate two arrays of names and sort them out without duplicate. When it shows on the screen I don't see the item 0 of my new array. I don't know why, in the console.log I see the item 0 which is "Alice". But, what I actually see on the webpage is 1. William, 2. Beatrice, 3. Charlie, 4. Charlotte, etc.

I am trying to reverse the following:

I'm creating a mini game using Raphael elements that is meant to create a pop-up when the player bumps with the "bullet", and so far the code works accordingly if I create each elements normally. For example, this:

For some reason, I'm getting an error that says conflicting types for ‘get_property’ because the function is reinitialized below. Why is this happening and how can I fix this?

I'm using Google Sheets and trying to confirm, using Google Apps Script, that a range is sorted by the last name (second column).
However, there are duplicates in the second column and, when performing the check, the data is re-sorting before the check, flipping the position of rows where the last name matches, at which point the lists don't match.
For instance, the Sheets range is as follows:

As you can see, rows {1,2} and {3,4} have the same last name. But I've sorted the data on Last Name from Sheets, so this should be correct. However, when I run the code it resorts and flips them, so that it sorts to:

and now, obviously, they do not match.

How can I check to see if a 2d array is sorted on a single column without having this happen where it attempts to re-sort the array?
