#T-SQL, 216 bytes

Before executing this MS-SQL Studio Management, press CRTL-t to show data as text. The height cannot be adjusted to exceed the number of elements in the input.

Because of the horrible implementation of STRING_AGG, the height variable will only work in MSSM. MS should have made a third optional parameter to include the order of the elements being concatenated.

The online version can only support adjustment of the width. Height will result in a funky result with multiple stacking shapes.

USE master
DECLARE @ table(v int,i int identity)
INSERT @ values
(0x06),(0x0F),(0xF3),(0xFE),(0x0E),(0x04),
(0x04),(0x1E),(0x3F),(0x7F),(0xE3),(0xC3),

This script will not show the correct shapes in the online version, so I made some minor adjustments to compensate. Try it online
