Detailed Explanation {{element[col]}} : : This defines a table cell that will contain data. *matCellDef=let element : This directive indicates that element will be a row data object. It is a template definition for the table cell. {{element[col]}} : This displays the value of the col property of the element object. : : This defines a column in the table. The col attribute is used to specify the name of the column. *ngFor=let col of displayedColumns : This directive creates a column for each item in the displayedColumns array. displayedColumns is an array that contains the names of the columns to be displayed. {{col}} : : This defines a header cell in the table. *matHeaderCellDef : This directive is used to define the content of the header cell. {{col}} : This displays the column name in the header. Combining everything together : The with *ngFor creates a set of columns based on displayedColumns . For each column a header cell ( ) and a data cell ( ) are defined. The header cell shows the column name while the data cell displays the value from the row data object ( element ) for the given column. Here’s how you might use the provided code snippet within a complete setup: {{col}} {{element[col]}} Explanation: : Defines the table and binds the data source to it. : Defines the header row for the table. : Defines the rows for the table. Data Source and Columns In your component you should define the displayedColumns and dataSource : export class YourComponent { displayedColumns: string[] = ['column1' 'column2' 'column3']; dataSource = [ { column1: 'Data 1' column2: 'Data 2' column3: 'Data 3' } { column1: 'Data 4' column2: 'Data 5' column3: 'Data 6' } // More data objects... ]; }
