Loader inside a table <td>

Question

I am trying to put loader inside a table but it is not working. The issue is when I am putting div inside a td, the tabular format is not working.

When I inspected the elements the div was outside of the table.

.loader {
  background: #000;
  background: radial-gradient(#222, #000);
  bottom: 0;
  left: 0;
  overflow: hidden;
  position: fixed;
  right: 0;
  top: 0;
  z-index: 99999;
}
.loader-inner {
  height: 60px;
  left: 0;
  position: absolute;
  right: 0;
  width: 100px;
}
.loader-line-wrap {
  animation: spin 2000ms cubic-bezier(.175, .885, .32, 1.275) infinite;
  box-sizing: border-box;
  height: 50px;
  left: 0;
  overflow: hidden;
  position: absolute;
  top: 0;
  transform-origin: 50% 100%;
  width: 100px;
}
.loader-line {
  border: 4px solid transparent;
  border-radius: 100%;
  box-sizing: border-box;
  height: 100px;
  left: 0;
  margin: 0 auto;
  position: absolute;
  right: 0;
  top: 0;
  width: 100px;
}
.loader-line-wrap:nth-child(1) {
  animation-delay: -50ms;
}
.loader-line-wrap:nth-child(2) {
  animation-delay: -100ms;
}
.loader-line-wrap:nth-child(3) {
  animation-delay: -150ms;
}
.loader-line-wrap:nth-child(4) {
  animation-delay: -200ms;
}
.loader-line-wrap:nth-child(5) {
  animation-delay: -250ms;
}
.loader-line-wrap:nth-child(1) .loader-line {
  border-color: hsl(0, 80%, 60%);
  height: 90px;
  width: 90px;
  top: 7px;
}
.loader-line-wrap:nth-child(2) .loader-line {
  border-color: hsl(60, 80%, 60%);
  height: 76px;
  width: 76px;
  top: 14px;
}
.loader-line-wrap:nth-child(3) .loader-line {
  border-color: hsl(120, 80%, 60%);
  height: 62px;
  width: 62px;
  top: 21px;
}
.loader-line-wrap:nth-child(4) .loader-line {
  border-color: hsl(180, 80%, 60%);
  height: 48px;
  width: 48px;
  top: 28px;
}
.loader-line-wrap:nth-child(5) .loader-line {
  border-color: hsl(240, 80%, 60%);
  height: 34px;
  width: 34px;
  top: 35px;
}
@keyframes spin {
  0%, 15% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(360deg);
  }
}

<table>
  <tr>
    <td>1</td>
  </tr>
  <tr>
    <td>
      <div id="preloader" class="loader">
        <div class="loader-inner">

If you need to contain the loading graphic within the <td> then you should not use fixed positioning.

Here is one solution. Remove the fixed positioning and related properties. Set positioning to relative along with a height and width for .loader.

.loader {
  position: relative;
  background: #000;
  background: radial-gradient(#222, #000);
  overflow: hidden;
  z-index: 99999;
  width: 100px;
  height: 100px;
}
.loader-inner {}
.loader-line-wrap {
  animation: spin 2000ms cubic-bezier(.175, .885, .32, 1.275) infinite;
  box-sizing: border-box;
  height: 50px;
  left: 0;
  overflow: hidden;
  position: absolute;
  top: 0;
  transform-origin: 50% 100%;
  width: 100px;
}
.loader-line {
  border: 4px solid transparent;
  border-radius: 100%;
  box-sizing: border-box;
  height: 100px;
  left: 0;
  margin: 0 auto;
  position: absolute;
  right: 0;
  top: 0;
  width: 100px;
}
.loader-line-wrap:nth-child(1) {
  animation-delay: -50ms;
}
.loader-line-wrap:nth-child(2) {
  animation-delay: -100ms;
}
.loader-line-wrap:nth-child(3) {
  animation-delay: -150ms;
}
.loader-line-wrap:nth-child(4) {
  animation-delay: -200ms;
}
.loader-line-wrap:nth-child(5) {
  animation-delay: -250ms;
}
.loader-line-wrap:nth-child(1) .loader-line {
  border-color: hsl(0, 80%, 60%);
  height: 90px;
  width: 90px;
  top: 7px;
}
.loader-line-wrap:nth-child(2) .loader-line {
  border-color: hsl(60, 80%, 60%);
  height: 76px;
  width: 76px;
  top: 14px;
}
.loader-line-wrap:nth-child(3) .loader-line {
  border-color: hsl(120, 80%, 60%);
  height: 62px;
  width: 62px;
  top: 21px;
}
.loader-line-wrap:nth-child(4) .loader-line {
  border-color: hsl(180, 80%, 60%);
  height: 48px;
  width: 48px;
  top: 28px;
}
.loader-line-wrap:nth-child(5) .loader-line {
  border-color: hsl(240, 80%, 60%);
  height: 34px;
  width: 34px;
  top: 35px;
}
@keyframes spin {
  0%, 15% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(360deg);
  }
}
table td {
  border: 1px solid #CCC;
}

<table>
  <tr>
    <td>1</td>
  </tr>
  <tr>
    <td>
      <div id="preloader" class="loader">
        <div class="loader-inner">
          <div class="loader-line-wrap">

    </td>
  </tr>
