How to carry the cell formatting from the source worksheet to a destination worksheet

I have defined a cell with a custom format with a value of '#0.00 " in"'.  Entering in a number value (.e.g. 1, displays a value of "1.00 in".  However, on a separate worksheet that references the source worksheet, the formatted cells do not make their way across resulting in "1" displaying in the destination worksheet.  How can I get the formatting from the original cell to carry over to the destination worksheet given a LET statement is used to generate the destination worksheet contents???

=LET(
table, PI_Package!$A$1:$HZ$1600,
head,TAKE(table,1),
data,FILTER(DROP(table,6),
