Is there any way to move above text into the below table's second cell in InDesign using JavaScript

In my InDesign document there are many tables, each table is on separate page with autoflowing text. There is a text above each table without paragraph returns. I want that text to move from there to table's second cell. This I want to do for all the tables in my active document. Basically I need to move text from other place into InDesign table. Can someone please help. Manually doing this is very time consuming and panic. There are many tables in my InDesign document.

this is the what I am expecting which is shown in attached screenshot

Select the text frame and try to run this code:

var story = app.selection[0].parentStory;
var pgfs = story.paragraphs;

for (var i=0; i<pgfs.length; i++) {
    if (pgfs[i].tables.length == 0) continue;

    var table = pgfs[i].tables[0];
    var cell = table.rows[0].cells[1];
    var contents = pgfs[i].lines[0].contents;

    app.findTextPreferences = NothingEnum.NOTHING;
    app.changeTextPreferences = NothingEnum.NOTHING;
    app.findTextPreferences.findWhat = contents;
    app.changeTextPreferences.changeTo = '';
    pgfs[i].changeText();

    cell.contents = contents;
}

Or, even simpler solution without changeText():

var story = app.selection[0].parentStory;
var pgfs = story.paragraphs;

for (var i=0; i<pgfs.length; i++) {
    if (pgfs[i].tables.length == 0) continue;
    pgfs[i].tables[0].rows[0].cells[1].contents = pgfs[i].lines[0].contents;
    pgfs[i].lines[0].contents = '';
}

Update

To move the footnotes you can try this:

var story = app.selection[0].parentStory;
var pgfs = story.paragraphs;

app.findGrepPreferences = NothingEnum.NOTHING;
app.findGrepPreferences.findWhat = "footnote\\s+\\d+.+"; // <-- your GREP

for (var i=pgfs.length-1; i>=0; i--) {              // loop backward
    if (pgfs[i].tables.length == 0) continue;       // skip if no table
    var finds = pgfs[i].findGrep();
    if (finds.length == 0) continue;                // skip if noting was found
    pgfs[i].insertionPoints[-1].contents = finds[0].contents;
    finds[0].contents = '';
}
