I like to insert two or multiple lines of text in to a table cell.

I'm using SetText method from ITable. The code is like below:

SetText(Row, Column, "first_line\\\\second_line"), but it shows first_line\\second_line in Draftsight.

I also tried \\n instead, but the result becomes first_line\\nsecond_line.

In addition, is there any way to modify the font of all table cells at once?

I checked API document, but it only mentions modifying the font cell by cell.

Thanks for the advice.
