Answer 1

You have missed some quotes

please use this code

string html=""; 
html += "<table>";
html += "<tr><th>" + "A" + "</th><th>" + "B" + "</th><th>" + "C" + "</th></tr>";
html += "<tr><td>" + "0" + "</td><td>" + "1" + "</td><td>" + "2" + "</td></td>"+"<input type='checkbox' name ='chk1' /> "  +"</td>  </tr>"; 
html += "</table>";

Answer 2

It appears that you're missing a quote, also you can get rid of some of the quotes (and rows):

string html=""; 
html += "<table>";
html += "<tr><th>A</th><th>B</th><th>C</th></tr>";
html += "<tr><td>0</td><td>1</td><td>2</td></td><input type=\"checkbox\" name =\"chk1\" /></td></tr>"; 
html += "</table>";

Answer 3

No need of concatenations, just put single quotes outside as given in the example below:

string html = ''; 
html += '<table>';
html += '<tr><th>A</th><th>A</th><th>C</th></tr>';
html += '<tr><td>0</td><td>1</td><td>2</td></td><input type="checkbox" name ="chk1"  /></td></tr>'; 
html += '</table>';
