Create HTML table from JavaScript object

I am attempting to create a table with JSON data, and my code runs error free, but when the code completes, no table is created on the page.

 api Data returns data in this format

{"Product":"RST-9042","Quantity":121}{"Product":"LMN-1017-KN","Quantity":"0"}{"Product":"YZH-2117","Quantity":13}

What piece am I missing here?

btnSubmit.onclick = async function() {
    const customerSelect = document.getElementById('customers');
    const selectedCustomer = customerSelect.selectedOptions[0].value;
    const intCustomer = parseInt(selectedCustomer);
    if ([1, 2, 3].includes(Number(intCustomer))) {
         await fetch(‘Ce.php?customer=' + intCustomer)
            .then(async (result) => {
                const apiData = result;
                //console.log(wooData);
                await generateTable(apiData);
                if (result.status != 200) {
                    throw new Error("Bad Server Response");
                }
                return result.text();
            })
            .then((response) => {
                console.log(response);
            })
            .catch((error) => {
                console.log(error);
            });
}
async function generateTable(apiData) {
    //Create a HTML Table element.
    const table = document.createElement("TABLE");
    table.border = "1";

    //Get the count of columns.
    const columnCount = apiData;

    //Add the header row.
    let row = table.insertRow(-1);
    for (const i = 0; i < columnCount; i++) {
        const headerCell = document.createElement("TH");
        headerCell.innerHTML = apiData[i];
        row.appendChild(headerCell);
    }

    //Add the data rows.
    for (const i = 1; i < apiData.length; i++) {
        row = table.insertRow(-1);
        for (const j = 0; j < columnCount; j++) {
            const cell = row.insertCell(-1);
            cell.innerHTML = apiData[i][j];
        }
    }

    const dvTable = document.getElementById("dvData");
    dvTable.innerHTML = "";
    dvTable.appendChild(table);
}
