This is probably a quick hack (a bit messy), but here's a wiki table serialization for your preparation:

let table=document.querySelector("table[class^='wikitable']"),
    tableHeader=[...table.querySelector("thead tr").children].map(c=>"colSpan"in c?Array(+c.colSpan).fill(c.innerText):c.innerText).flat(),
    tableBody=table.querySelector("tbody");
console.log([...tableBody.children].map(e=>{
	let c=[...e.children],a=[];
	for(let i=0;i<c.length;i++){
		if("colSpan"in c[i]){
			for(let j=0;j<+c[i].colSpan;j++)a.push(c[i].innerText||null);
		}else{
			a.push(c[i].innerText||null);
		}
	}
	let o={};
	for(let i=0;i<a.length;i++){
		if(tableHeader[i]in o){
			if(typeof o[tableHeader[i]]==="string"){
				o[tableHeader[i]]=[o[tableHeader[i]],a[i]];
			}else{
				o[tableHeader[i]].push(a[i]);
			}
		}else{
			o[tableHeader[i]]=a[i];
		}
	}
	return o;
}));

You could also rewrite the last part as such:

return tableHeader.reduce((o,h,i)=>{
	if(h in o)
		if(typeof o[h]==="string")o[h]=[o[h],a[i]];else o[h].push(a[i]);
	else o[h]=a[i];
	return o;
},{});
