	let row = Math.floor(Math.random() * 10) + 1;
	let col = Math.floor(Math.random() * 10) + 1;
	document.write("row: " + row + ", col: " + col);
	document.write("<br>");
	document.write("<table>");
	for(let r = 1; r <= row; r++) { //행
		document.write("<tr>");
		for(let c = 1; c <= col; c++) { //열
			document.write("<td>" + `${r}행 ${c}열` + "</td>");
		}
