I also have this issue. Is there a fix for it?

Still exists in CDK/Material v16.0.0.

It is still an issue. Even though I am setting the fixedLayout property to true on the Material Table, the default table-layout: auto gets applied over 'table-layout: fixed'.

This issue has been around since the v15 update and still a problem in v16.

Example

After some investigation in the table.scss I found this issue According to the issue, the additional 'table-layout: auto' override was added in order make the Material Table backwards compatible, since the browser default is 'auto'.

However, if someone wants to apply 'fixed' to the table there is no way to do it right now. Setting the 'fixedLayout' property to 'true' will bind the '.mdc-table-fixed-layout' to the table. This class however does not apply any styles.

In order to apply 'fixed' table layout I had to add a custom css workaround rule in my application:

.mat-mdc-table.mdc-table-fixed-layout {
    table-layout: fixed;
}

h3. Proposal If backwards compatible should be maintained, the default table-layout should be set to 'auto' without an overriding class. Then when fixedLayout addes the '.mdc-table-fixed-layout' class to the table 'table-layout: fixed' should override the default table-layout.

Still an issue with v17 of Angular Material/CDK.
