treetable | Dynamic Table Builder Directive for angular | Grid library

I have the following field

I am trying to convert a list into a tree structure for a primeng TreeTable.

I'm facing this issue, I would like to order each sub-items of my treeTable but where the RightNeighbourTaskUUID is equal to the UUID of the other item,

So if the item is on the top, his LeftNeighbourTaskUUID would be null, and if the item is bottom, the LeftNeighbourTaskUUID would be null, and in between, each items must be ordered where his UUID is equal to the RightNeighbourTaskUUID of the next item in the array

So each child item can have one uniq LeftNeighbourTaskUUID and/or unique RightNeighbourTaskUUID, or those can be null if it's a uniq child .

Sorry about my MS Paint skills,(I've used ID and leftID and rightID in the picture just to help give a visual representation) just to help understanding how my tree Table is built

So I've made a search and sort function, where I will explore the children's and sort them if the children's length is higher than 1 , as no need to sort if the length is 1 or less

I am trying to calculate totals for each node of a tree structure, Calculating the total depends on roll up type

I have Structure like below

• if node type is current list = Look to current node, no need I go down in the tree
• if node type is child = ignore the current node and go down
• if node type is current and child = I include the current node and go down

Assume my Starting Point will be B1 : so the total score will be = (20 +40 +110 +60 +90)

Assume my Starting Point C2 : Score is 110

I managed to get all children but when it comes to the rollup I get stuck please help

Sample Data Script

I'm trying to create a tree structure view from a json model using SAPUI5.
I haven't found solutions on the internet so this is why I'm asking here.
Basically, despite having used the right code over and over again, It fails to load the TreeTable.js file, I have tried using multiple codes but no luck.
I am loading the TreeTable on a Dialog. This is the code:

I am trying to dynamically bind the change events in the PrimeNG TreeTable, by declaring functions on my columns. The change event binding doesn't seem to work inside of TreeTable when I try to do it dynamically with my columns. I can get it to work if I declare the function on the angular component and the bind it.

I am using treeTable from primeNG. I wanted to know how to change default expand and collapse icon.

I tried doing so... but I am not sure if I'm doing it the right way. I just want to replace those default expand/collapse icons to plus/minus. How do I go about?

I tried following.. but it didn't help.
