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... ]; }
