No straight-bar or slant shape spells D 13 on the lap steel in C6 tuning (C-E-G-A-C-E). The chord is built from D, E, F#, A, B, C, but a steel bar can only sound what the open strings become under it: at every fret, and on every short slant the lap steel allows, the strings that land on this chord's tones leave out a tone it needs, or too few of them ring.
The E13 tuning (B-D-E-G#-C#-E) has one: Bar 10.
So this page charts nothing rather than a hand-fretted grip no steel can hold. The lap steel chord pages that do chart shapes list only straight bars and short declared slants in C6 tuning (C-E-G-A-C-E).
