How to do this custom table

We are required to populate a table with a custom bar need to show which slot is booked. Refer to the image below. Can anyone share the idea on how to develop this custom view or let me know, that it cannot be done? Especially on the time panel

Hi,
You can use a style provider for the table.
For example, if the cell is fully in the date range - make background red. If the cell is in the border of the date range - make background rose.

See examples in the doc:
