我创建了一个引导表，其中将动态添加行。但是表格主体和表格标题对齐方式不匹配，如下面的代码段所示。

＆＃13;
＆＃13; 
function display() {


  var tableRef = document.getElementById('myTable1').getElementsByTagName('tbody')[0];
  var rowsAdd = tableRef.insertRow(tableRef.rows.length);

  //    var m = moment().format('YYYY-MM-DD h:mm a');

  var newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<input type='text'  form ='form1'  class= 'form-control input-sm' value=' ' id = 'typeofdr' name= 'typeofdr'  required>";
  newCell.style.width = '100px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' '  type='text' id = 'drugname' name= 'drugname'  required> </td></tr>";
  newCell.style.width = '100px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' ' type='text' id = 'strdrug' name= 'strdrug'  required> </td></tr>";
  newCell.style.width = '100px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' ' type='text' id = 'dosage' name= 'dosage'  required> </td></tr>";
  newCell.style.width = '50px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'dm' value= 'on' name= 'dm'  ><input type='hidden' name='dm' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'da' name= 'da' value='on'  ><input type='hidden' name='da' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'de' name= 'de' value='on' ><input type='hidden' name='de' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'dn' name= 'dn' value='on' ><input type='hidden' name='dn' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><select  form ='form1' class= 'form-control input-sm' value=' ' id = 'baf' name= 'baf'  required><option>Before</option><option>After</option></select> </td></tr>";
  newCell.style.width = '90px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' ' type='text' id = 'totn' name= 'totn'  required> </td></tr>";
  newCell.style.width = '70px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' ' type='text' id = 'nofdays' name= 'nofdays'  required> </td></tr>";
  newCell.style.width = '50px';



  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td class='tds'><i class='fa fa-trash-o' font-size:20px'  onclick='deleteRow(this)'></i></td></tr>";
  newCell.style.width = '50px';



}

function deleteRow(r) {

  var i = r.parentNode.parentNode.rowIndex;
  document.getElementById("myTable1").deleteRow(i);


}
＆＃13; 
table.alpha th {
  background-color: #009999;
  color: white;
}

table.alpha .tbalpha {
  height: 200px;
  overflow-y: auto;
}

table.alpha .thalpha,
.tbalpha {
  display: block;
}

</div>

如上面的代码片段所示，表格列标题和表格主体列行未正确对齐i，表格单元格并不完全低于其相应的标题单元格。我猜css可能有问题，但是如果在css中移除display：block，即使设置了高度，表体高度也会减小（在上面的css代码中，tbody height设置为200px）。

2 个答案:

答案 0 :(得分：0)

这是因为您正在改变tbody和thead显示的方式：

table.alpha .thalpha, .tbalpha {
    display: block;
}

如果删除它，列将对齐

答案 1 :(得分：0)

您不能更改display的{​​{1}}属性，因为它的默认属性为tbody。删除display: table-row-group会使其正确对齐。

display
function display() {


  var tableRef = document.getElementById('myTable1').getElementsByTagName('tbody')[0];
  var rowsAdd = tableRef.insertRow(tableRef.rows.length);

  //    var m = moment().format('YYYY-MM-DD h:mm a');

  var newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<input type='text'  form ='form1'  class= 'form-control input-sm' value=' ' id = 'typeofdr' name= 'typeofdr'  required>";
  newCell.style.width = '100px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' '  type='text' id = 'drugname' name= 'drugname'  required> </td></tr>";
  newCell.style.width = '100px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' ' type='text' id = 'strdrug' name= 'strdrug'  required> </td></tr>";
  newCell.style.width = '100px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= 'form-control input-sm' value=' ' type='text' id = 'dosage' name= 'dosage'  required> </td></tr>";
  newCell.style.width = '50px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'dm' value= 'on' name= 'dm'  ><input type='hidden' name='dm' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'da' name= 'da' value='on'  ><input type='hidden' name='da' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'de' name= 'de' value='on' ><input type='hidden' name='de' value='off' form='form1'> </td></tr>";
  newCell.style.width = '37.5px';

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td><input  form ='form1' class= ''  type='checkbox' id = 'dn' name= 'dn' value='on' ><input type='hidden' name='dn' value='off' form='form1'> </td></tr>";

  newCell = rowsAdd.insertCell();
  newCell.innerHTML = "<tr><td class='tds'><i class='fa fa-trash-o' font-size:20px'  onclick='deleteRow(this)'></i></td></tr>";
  //newCell.style.width = '50px';



}

function deleteRow(r) {

  var i = r.parentNode.parentNode.rowIndex;
  document.getElementById("myTable1").deleteRow(i);


}
table.alpha th {
  background-color: #009999;
  color: white;
}

table.alpha {
  display: block;
  height: 300px;
  overflow-y: auto;
}
