Components: Document multiTemplateDataRows

[woteska]

BUG

What is the expected behavior?

I can get the index of a row.

What is the current behavior?

Indexes are always undefined.

What are the steps to reproduce?

https://angular-material2-issue-xxupf5.stackblitz.io

What is the use-case or motivation for changing an existing behavior?

Highlighting a row ; Adding drag-and-drop feature to my project; etc.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

I only tried the latest Material.
OS: Win10
Others:

Is there anything else we should know?

Angular Material Basic Table works perfectly: https://angular-z4wbnd.stackblitz.io

Change "let i = index" for "let i = dataIndex"
It works.

/**

• Context provided to the row cells when multiTemplateDataRows is true. This context is the same
• as CdkCellOutletRowContext except that the single index value is replaced by dataIndex and
• renderIndex.
  */

Thanks buddy, it works!

I would suggest to complete the documentation (https://material.angular.io/components/table/api) with this very very important information if it is possible. It is missing of it and I found many users on forums who needs the index of the rows.

Apart from me issue can be closed. Thanks again!

Documentation still not updated?

[Akshar11]

Please update the documentation .

I agree it would be nice to have this information in the documentation since people can spend a lot of time debugging without knowing this is the property causing the problem and not having a way to search for the issue (me included)
