Hi,
I am new to Power Automate. I am preparing a table to be sent as an email to a list of clients. The table data comes from Query on a PowerBI dataset. And it contains availability of clients for two weeks. I created HTML Table based on this data and it shows the table as below:

I have a select Data Operation to choose the fields from data source and an HTML table which is being created automatically based on the select.
I want to edit this table so it will be clearer. Would like to show every two record of the table in grey like below:

I put a loop to increment a variable by two and used append to array variable to format based on that but it does not work properly.
Can someone help me on this?
Thanks
