Hi @gurleenm ,
I created the flow in my environment. Please give it a try.
My Excel1 File Table contains following columns: VideoId,Name,State,Description,PublishedDate,LastViewDate,Size(inBytes),Views,Likes,ContentType,PrivacyMode,Creator,Owners,ContainerId,ContainerName,ContainerType,ContainerEmailId,ContainerAadId,MigratedDestination,ContainerVideosInClassicUI,IsEligibleForMigration
My Excel2 File Table contains the column: containeremailid
When the flow runs, it will get all the records of Excel2 and checks for the records that have same ContainerEmailId and if it finds the records, the flow will add them in the Table and send the table via email to that person. Please Find the input and output at the end.
Please follow these steps provided below.
Here is the full screenshot of the flow:

Steps:
1. Please initialize a variable of Array Type
2. Add "List rows present in a table" action and configure it for "Excel2". Also, please make sure to add the filter query to filter empty records of the table.

3. Add a apply to each and In Appy to each add "List rows present in a table" and configure it for Excel2. Please make sure to add the Filter Query here.

4. Add a Condition to check the records exists or not. If condition is false it will move to the next iteration of the loop.
If condition is true, it will iterate of all the records of excels 1 which are having the same ID of current item and Append the Value in an Array variable.
Note: In Append to array Variable Action, I'm only using two values "VideoId" and "Name". please configure similarly for all values that you want in the Table.
{
"VideoId": "",
"Name": ""
}

5. Add Create an HTML table Action and add the "VarAppend" Variable in from Dynamic content in "From". Refer to image below.
6. Add Compose Action and Paste this CSS for the Table Styling:
<style>
Table {
font-family: Arial, Helvetica, sans-serif;
background-color: #EEEEEE;
border-collapse: collapse;
width: 100%;
}
Table td, Table th {
border: 1px solid #ddd;
padding: 3px 3px;
}
Table th {
font-size: 15px;
font-weight: bold;
padding-top: 12px;
padding-bottom: 12px;
text-align: left;
background-color: #1C6EA4;
color: white;
}
</style>
Note: You can Modify it Accordingly.

7. Add a Send an email Action and added the values of "To", "Subject" and "Body".
