angular - PrimeNg p-datatable is not picking the provided template -


i have use case wherein have varying number of rows , columns table. not have information header names.

i trying use following implementation:

i fetch reference table using @viewchild('tableref ') tableref ; call service fetch columns list , assign as: tableref .columns = colarray;

this colarray contains objects having field , headers property automatically assigned table. (this working fine , can see header name in table)

i preparing array of objects data, objects have property name same field name picked colarray.

finally in html have:

<div class="col-sm-12 kill-padding table">     <p-datatable #tableref [value]="data" rowhover="true">         <p-column>             <ng-template ptemplate="body" let-col let-row="rowdata">               <div [ptooltip]="row[col.field]" tooltipposition="bottom">                 <h2>{{row[col.field]}}</h2>               </div>             </ng-template>         </p-column>     </p-datatable>   </div>

in template above far row[col.field] assigned string, gets displayed. if row[col.field] object template doesn't bind. believe template not @ picked, because when inspect html can't see custom tags.

i want bind data @ following level: <h2>{{row[col.field]['someproperty']['finalproperty']}}</h2>

i have used in following way: <h2>{{row[col.field].someproperty.finalproperty]}}</h2>

in each of above case object bound table , table shows [object object]

is not possible bind data in following manner. doing wrong here. kindly suggest..

what do, transform data receive make "readable" datatable.

first, should have data : 

let data = [     {name: 'ziggity', surname: 'zwooty', age: 16},      {name: 'bippity', surname: 'bopitty', age: 18},  ];

from data got, should properties of data : 

let keys = object.keys(data[0]); // ['name', 'surname', 'age']

now, in html, can repeat primeng component each key : 

    <div class="col-sm-12 kill-padding table">     <p-datatable [value]="data" rowhover="true">         <p-column *ngfor="let key of keys">             <ng-template ptemplate="body" let-row="rowdata">               <div [ptooltip]="row[key]" tooltipposition="bottom">                 <h2>{{row[key]}}</h2>               </div>             </ng-template>         </p-column>     </p-datatable>   </div>

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
