move a value out of the promise

i have this piece of code that populates a repeater and a table inside each element.
So far everything works but I have a table with 2 columns which must be respectively populated by 2 different databases.
To do this I have found a way to get the right field from the databases but I can’t move the second database variable into the array with the information of the first.

I tried to set an external variable, I tried with Object.assign () but nothing, what do I do?

$$w("#repeater1").onItemReady(($item, itemData, index) => {
                $item('#txtCategoryTitle').text = itemData.categoryName;
                $item('#txtCategoryDescription').text = itemData.categoryDescription;

                getTableVideo(itemData._id)
                    .then((lesson) => {

 let rowsData = [];
 for (var i = 0; i < lesson.length; i++) {
 let complete = '';

 getTableCompleted(lesson[i]._id, wixUsers.currentUser.id)
 .then((results) => {
 complete = results[0]; // this value is 'Yes'
   })
 rowsData.push({ 'name': lesson[i].videoName, 'completed': complete, '_id': lesson[i]._id });
 console.log(rowsData);

    }
 $item("#tableVideo").rows = rowsData; // insert into the table
 if (currentLessonNumber === undefined) {
                            $w('#btnResume').label = 'Begin course>';
                            $w('#btnResume').enable();
                        } else {
                            $w('#btnResume').enable();
                        }
                        $w('#repeater1').show("fade", { "duration": 500, "delay": 0 })

                    })

            });

output of the code:

completed: ""
name: "3"
_id: "c9ac7293-7d9f-4574-80e6-33571a75514c"

Sorry, but the code is a little bit messy and it’s hard to understand what exactly you’re trying to do. also you’re nesting promises instead of chaining them and that makes it even harder to read (and makes it prone to errors).
Try to edit your code + explain in words what you’re trying to do + highlight the spot in the code that makes you troubles.
