Answer 1

using css we can adjust specific column width which i put in below code.

user.component.css

table{
 width: 100%;
}

.mat-column-username {
  word-wrap: break-word !important;
  white-space: unset !important;
  flex: 0 0 28% !important;
  width: 28% !important;
  overflow-wrap: break-word;
  word-wrap: break-word;

  word-break: break-word;

  -ms-hyphens: auto;
  -moz-hyphens: auto;
  -webkit-hyphens: auto;
  hyphens: auto;
}

.mat-column-emailid {
  word-wrap: break-word !important;
  white-space: unset !important;
  flex: 0 0 25% !important;
  width: 25% !important;
  overflow-wrap: break-word;
  word-wrap: break-word;

  word-break: break-word;

  -ms-hyphens: auto;
  -moz-hyphens: auto;
  -webkit-hyphens: auto;
  hyphens: auto;
}

.mat-column-contactno {
  word-wrap: break-word !important;
  white-space: unset !important;
  flex: 0 0 17% !important;
  width: 17% !important;
  overflow-wrap: break-word;
  word-wrap: break-word;

  word-break: break-word;

  -ms-hyphens: auto;
  -moz-hyphens: auto;
  -webkit-hyphens: auto;
  hyphens: auto;
}

.mat-column-userimage {
  word-wrap: break-word !important;
  white-space: unset !important;
  flex: 0 0 8% !important;
  width: 8% !important;
  overflow-wrap: break-word;
  word-wrap: break-word;

  word-break: break-word;

  -ms-hyphens: auto;
  -moz-hyphens: auto;
  -webkit-hyphens: auto;
  hyphens: auto;
}

.mat-column-userActivity {
  word-wrap: break-word !important;
  white-space: unset !important;
  flex: 0 0 10% !important;
  width: 10% !important;
  overflow-wrap: break-word;
  word-wrap: break-word;

  word-break: break-word;

  -ms-hyphens: auto;
  -moz-hyphens: auto;
  -webkit-hyphens: auto;
  hyphens: auto;
}
