How do I center Angular Material table column headers and mat-cell content

Question

Can anyone provide a concise explanation of how to center (or move to the right) Angular Material table header and cell texts? There seems to be a lot about needing /deep/ and other versions, which may or may not be deprecated.

Answer 1

If no answer is working above then try this :

table {
  width: 100%;
}

mat-header-cell, mat-cell {
  justify-content: center;
}

or

angular material 2 table header center alignment
