Hello Aleksey.

Thank you for your purchase.

If you want to make all text appear bold, you can add this CSS to Custom JS and CSS:

.wpdt-c {
font-weight: bold !important;
}

If you want to apply that to only a specific column, you need to add a custom CSS class in column's settings:

So, if you add that class to columns "День" and "Место", you need to add that class in settings, and add this custom CSS:

.wpdt-c .bold {
font-weight: bold !important;
}

As for splitting the text in two rows, if you use the first option when creating a table (Create a table linked to an existing data source), you need to modify the Google Spreadsheet table to look like this:

8 921 988 46 03 (для мужчин)<br>8 921 303 86 46 (для женщин)

Or, if you use the third option (Create a table by importing data from data source) I believe it could be done manually, when you set the column edit input type to "Multi-line edit".

I hope this helps.

Best regards.
