At a glance
Explains Handsontable's physical, visual and renderable row and column coordinate spaces and how to convert between them with IndexMapper, for debugging misplaced rows or columns.
- Debugging a row or column that appears in the wrong position in Handsontable
- SKILL.md covers HidingMap vs TrimmingMap, IndexMapper API, Which coordinate to use and Gotcha: Filters +…, plus 2 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Converting between physical and visual indexes with IndexMapper
What it does
Physical indexes never change and always match the source data array; visual indexes change under filtering, sorting, trimming or moving, though a hidden row or column keeps its visual index; and renderable indexes are DOM positions that mostly stay internal to the rendering engine, which receives already-processed data and renders it from zero to N. A table pairs each coordinate with when to use it: physical for reading or writing source data and for persistent state like sort order, and visual for user-facing positions, selection and the public getDataAtCol API.
It distinguishes a HidingMap, used by hidden-columns and hidden-rows plugins, where the index stays in visual space but is skipped during rendering, from a TrimmingMap, used by trim-rows and filter plugins, where the index is removed from visual space entirely. A named gotcha is that the filters plugin's condition collection uses physical indexes while getDataAtCol takes visual ones, and with manual column move active the two orders diverge, so a conversion through IndexMapper's visual-to-physical or physical-to-visual methods is needed before crossing that boundary.
When your agent uses it
- Debugging a row or column that appears in the wrong position in Handsontable
- Converting between physical and visual indexes with IndexMapper
- Working out which coordinate space a Handsontable plugin uses
Example prompts
- “Rows appear shuffled after enabling manual column move with filters, which coordinate space is the bug in?”
- “Convert this physical row index to its visual index using IndexMapper.”
- “Which coordinate space does getDataAtCell use?”
What it can do on your machine
Read from SKILL.md and the folder at commit 68b5e97. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Handsontable Coordinate Systems loads about 721 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 246 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 246 words (~721 tokens).
“The public API mainly uses visual indexes, sometimes physical. Walkontable receives data already filtered, sorted, and trimmed and renders it 0 to N; it also uses "source index" and "render index" internally for virtualization.”
