Build HTML Table from three separate arrays?

I need to build an HTML table with three separate arrays with each column being one of my arrays. Is this possible? I feel like it but I seem to fail in implementing this. I've tried several different methods but I can't seem to wrap my head around this.

Hi @Jdemke 

 

Assuming all the arrays have same number of rows

This can be achieved

 

Arr1, Arr2, Arr3 are names of my 3 arrays which holds the data

 

First initialize a variable of type integer - call it index and initialize it to 0

Also initialize a variable of type array and call it arrFinal and initilizae it to []

 

then run a for loop on arr1 

within for loop

use append to array variable action

select arrFinal and then in Value create json for your columns

 

{

"Column1": item(),

"Column2": variables('arr2')[variables('index')],

"Column 3": variables('arr3')[variables('index')]

}

 

Bold are expressions

 

And then next step in for loop

increment the index variable by 1

 

after the loop completes, you should get a consolidated array of all your columns which you can create an html table from

Hi @Jdemke 

 

You would have to create a single array which holds all the data together in order to achieve that

 

createArray can be used to generate an array and you can add logic which links all 3 arrays together

But if there is no link then only option would be to create 3 seperate html tables

I know how to combine the arrays into a single one but is there a way to keep them in order for the first item in the array is followed by the first item in the second array, etc.. ?

Thanks, I got all that but I don't know how to build the expression with the json you posted. I tried it a few ways but it says invalid expression. Am I missing something?

Hi @Jdemke 

 

In you append to array variable

 

just use

{

"Column1": item(),

"Column2": variables('arr2')[variables('index')],

"Column 3": variables('arr3')[variables('index')]

}

 

 

no need to use json function

Thank you, I appreciate the help!
