我怎样才能在使用Javascript与<td>表document.getElementById("Table").rows[i].cells[j]写？或任何其他可能的方式？
我想写的东西与JavaScript中<td></td>。我用这个代码的第一部分，但是当我再次使用它，它没有工作。如果有帮助，是用JavaScript生成的表格：
var cell = document.createElement("td");
var cellText = document.createTextNode(i+j);
cell.appendChild(cellText);
见create table using JavaScript：
var td = document.createElement('td');
td.appendChild(document.createTextNode('text'))
这是一个工作例子，在该标记创建一个基本的表格。
// save the table to a var
var table = document.getElementById('my_table');
// save table body to a var. select the first occurrence of tbody element with [0]
var tableRef = table.getElementsByTagName('tbody')[0];
// save new row tr to a variable. this generates a tr
var newRow = tableRef.insertRow(tableRef.rows.length);
// insert a cell into newRow at index 0, 1, and 2, the td's for this row
var newTD1 = newRow.insertCell(0);
var newTD2 = newRow.insertCell(1);
var newTD3 = newRow.insertCell(2);
// create a text node for the TD
var tdText1 = document.createTextNode('cell text 1');
// add the text to the newly generated newTD1
newTD1.appendChild(tdText1);
// create a text node for the TD
var tdText2 = document.createTextNode('cell text 2');
// add the text to the newly generated newTD2
newTD2.appendChild(tdText2);
// create a text node for the TD
var tdText3 = document.createTextNode('cell text 3');
// add the text to the newly generated newTD3
newTD3.appendChild(tdText3);/* table styles */
#my_table {
border-collapse: collapse;
border: 4px solid black;
margin: 0 auto;
text-align: center;
}
/* table tr, td styles */
#my_table th,
#my_table td {
border: 2px solid black;
}
/* table header styles */
#my_table th {
background-color: #33c6ff;
color: #000;
width: 33%;
