Table creator

const data=[
    {
        name: "Kapil",
        age:  21,
        status: "Active"
    },
    {
        name: "John",
        age:  28,
        status: "Inactive"
    },
    {
        name: "Deos",
        age:  18,
        status: "Active",
        testing: 'Gooo!!'
    }
]

const createTable=function(data){
const table = document.createElement("table");
const header = document.createElement("tr");
const keys=Object.keys(data[0])
console.log(keys)
for(const key of keys){
    const th=document.createElement("th");
    th.appendChild(document.createTextNode(key));
    header.appendChild(th);
}
table.appendChild(header);
const len=data.length
for(const row of data) {
    const tr = document.createElement("tr");
    for(const key of keys){
        const td = document.createElement("td");
        const content=row[key] ||''
        td.appendChild(document.createTextNode(content));
        tr.appendChild(td);
        delete row[key]
    }
  /****
  you can omit next cycle if all object have the same structor or if the first element of collection have all fields
  ****/
    for(const key in  row){
        const th=document.createElement("th");
        th.appendChild(document.createTextNode(key))
        keys.push(key)
        header.appendChild(th);
        const td = document.createElement("td");
        const content=row[key] ||''
        td.appendChild(document.createTextNode(content));
        tr.appendChild(td);
    }
    table.appendChild(tr);
}
return table

}
