Angular Material Table Not Rendering Datasource Rows Stack Overflow The table will take the array and render a row for each object in the data array.,an alternative approach to providing data to the table is by passing an observable stream that emits the data array to be rendered each time it is changed. I use mat table in several of my projects, and all it really needs is an array of objects with the same properties. just have your html point directly at your data and see what it does. Rather than using the data property of the data source, you can use the connect stream which is what the table uses to know what to render. by applying the async pipe, you automatically gain the benefits of automatic change detection. When passing an array to the table, it will only re render if the array reference is changed because it is based on the principle of using an immutable data array.

A footer row can be added to the table by adding a footer row definition to the table and adding footer cell templates to column definitions. the footer row will be rendered after the rendered data rows. Have a look at the api, pretty sure your data source is supposed to be an observable. if it’s not an observable and data is not there on first render (viewinit) then it’ll act as though data is empty until a next is emitted. When the data source emits an array on that stream, the table re renders its rows. in your case, you are adding to the array, but not emitting anything new so the table is not signaled to re render. Looks like your mixing the native table elements with the mat table element. you should replace your td, th and tr elements with mat cell, mat header cell and mat row respectively. if you want to use the native table approach, use a native table element with the mat table as an attribute.
