What I’m trying to do
Using dataviewjs, create a list of tables that group each condition by diagnostic modality.
In the attached photo, I want the notes “leiomyoma (ml)” and “adenomyosis” to be grouped under a similar header “transabdominal UTZ”, and “adenomyosis” and “urethral diverticulum” to be grouped under a similar header “transvaginal UTZ”
Things I have tried
The code I used for the picture above is as follows:
let pages = dv.pages('"2023zettelkasten/23.07.30"')
let grps = pages.groupBy(p => p.dxVia)
for (let group of grps.sort(g => g.length, 'asc'))
{
dv.header(3, dv.array(group.key).join(", "));
dv.table(["Differential", "Condition", "Treatment"], group.rows .sort(k => k.file.ctime, 'ascending').map(k => [dv.span(k.differential), dv.header(3, k.file.link), dv.span(k.treatment)]))
}
I do not have background with javascript and tried incorporating flatMap to get it to flatten the headers but I just end up with the flattened headers and no display. The “best attempt” I have achieved so far is this:
Which uses this code:
let pages = dv.pages('"2023zettelkasten/23.07.30"')
let dlabel = pages.flatMap(p => p.dxVia)
let grps = dlabel.groupBy(p => p)
for (let group of grps.sort(g => g.length, 'asc'))
{
dv.header(3, dv.array(group.key).join(", "));
dv.table(["Differential", "Condition", "Treatment"], group.rows.rows .sort(k => k.file.ctime, 'ascending').map(k => [dv.span(k.differential), dv.header(3, k.file.link), dv.span(k.treatment)]))
}
Attached is a sample of the frontmatter for the notes leiomyoma (ml) and adenomyosis, respectively:
---
cause: [vitamin D deficiency, hypoxia leading to transformation of smooth muscle cell into myoma, familial tendency]
differential: [adenomyosis, pregnancy, ovarian mass, gestational trophoblastic diseases that cause globular uterus]
feature: "[[WIP - Relational databases as notes#Table 17 - Classification of leiomyoma]]"
location:
treatment:
riskFactor: [after menarche]
dxVia: [physical exam, transvaginal UTZ, transabdominal UTZ]
buzzwords: [most common benign tumor of muscular origin, benign monoclonal tumors of muscle cell origin, myoma, fibromyoma]
---
---
cause: null
differential: null
feature: [<i>endometrial</i> glands and stroma are present within the myometrium also]
location: null
treatment: [hysterectomy, medical management for pain and bleeding (Same as myoma)]
riskFactor:
dxVia: [transvaginal UTZ, transabdominal UTZ, MRI to differentiate from myoma]
buzzwords: null

Any insight and help is much appreciated 
Cheers!
