        "content": "Here\u2019s how WCAG (Web Content Accessibility Guidelines) and related best practices treat tables, especially in the context of accessibility testing. Then I\u2019ll answer whether you\u2019d mark such a test \u201cdNA\u201d (\u201cdoes Not Apply\u201d) in the case you described.\n\n---\n\n## Key WCAG Guidelines on Tables\n\n1. **Definition: Data tables vs layout tables**  \n   - *Data tables* are used to present tabular relationships (rows and columns of related data), where row headers, column headers, or both are present. ([w3.org](https://www.w3.org/WAI/WCAG21/Techniques/html/H51?utm_source=openai))  \n   - *Layout tables* are used purely for visual positioning, not for presenting data relationships. They typically don\u2019t have headers. ([accessibleweb.com](https://accessibleweb.com/question-answer/how-are-layout-tables-and-data-tables-different/?utm_source=openai))\n\n2. **Required markup**  \n   - Data tables must use proper semantic HTML: `<table>`, `<tr>`, `<th>` for headers, and `<td>` for data cells. ([w3.org](https://www.w3.org/WAI/WCAG21/Techniques/html/H51?utm_source=openai))  \n   - Headers should be clearly associated with their data cells, using `scope`, `id`/`headers`, etc., especially for complex tables. ([w3.org](https://www.w3.org/WAI/WCAG21/Techniques/html/H51?utm_source=openai))\n\n3. **WCAG Criterion 1.3.1 \u2014 Info and Relationships**  \n   - Requires that relationships conveyed visually (e.g. via rows/columns in a data table) are also programmatically determinable. This depends on proper structure and markup. ([w3.org](https://www.w3.org/WAI/WCAG21/Techniques/html/H51?utm_source=openai))\n\n4. **When tables are layout tables**  \n   - If the table is used purely for layout, it should *not* use data table markup (like `<th>` or `scope`) that would signal it's a data table to assistive technologies. This prevents confusion. ([webaim.org](https://webaim.org/techniques/tables/?utm_source=openai))  \n    \n---\n\n## Applying to Your Case\n\nYou said:\n\n> \u201cI see a data table on a website, but no layout table or any misconfigured table that was intended to be a layout table.\u201d\n\nTo break this down:\n\n- **You have a table that visually looks like a data table.**  \n- **It does *not* have markup errors or is not misused layout-wise.**  \n\nGiven that, some possibilities:\n\n- It *could be* a correctly implemented data table.  \n- Or it could be a table without correct markup or headers etc.\u2014which would fail some accessibility requirements.\n\n---\n\n## What \u201cdNA\u201d Means in Testing\n\nIn many accessibility or audit frameworks:\n\n- \u201c**dNA**\u201d often means \u201cdoes *not apply*\u201d\u2014i.e., a particular test criterion is not applicable in this context.  \n- You use dNA only when the test clearly does *not* apply.  \n\nFor example: If a table is genuinely only for layout (no data relationships), then tests for data table header markup might be dNA for that layout table, because requirements for data tables don\u2019t *apply* to layout tables.  \n\n---\n\n## So, Should You Mark the Test as DNA in Your Situation?\n\nNo \u2014 based on what you said (\u201csee a data table \u2026 but no layout table or misconfigured layout table\u201d), you *should not* mark the test as dNA, provided the content really is a data table and should meet the criteria for data tables. If the table is serving to present relationships in rows/columns, then the following tests *do apply*:\n\n- It should have `<th>` elements for headers.  \n- Headers must use `scope` or `id`/`headers` to associate properly with the data cells.  \n- It should pass WCAG 1.3.1 (info & relationships must be programmatically determinable).\n\nYou\u2019d only mark as dNA if it really *is* a layout table (i.e., purely visual, no data relationships)\u2014but that doesn\u2019t seem to be your case.\n\n---\n\n## Summary\n\n- If the table is *displaying data* (rows/columns, relationships) even if you see no misconfiguration, the accessibility rules for data tables **do apply**.  \n- Therefore, you shouldn't mark \u201cthe test\u201d as dNA for that table\u2014because tests like checking for headers, proper markup, etc., are relevant and required.  \n- If instead the table is purely used for layout, then yes, tests for data tables (headers, etc.) can be marked dNA\u2014because that requirement doesn\u2019t apply to layout tables.  \n\n---\n\nIf you want, I can help walk through the checklist for testing that exact table\u2014headers, markup, etc.\u2014to see if it passes or fails. Do you want me to do that?"

([section508coordinators.github.io](https://section508coordinators.github.io/ACRT/Resources/Trusted%20Tester%20Test%20Process%20v5.1.3.pdf?utm_source=openai))\n\nThe Condition reads:\n\n> *Applicability*: This test **does not apply (DNA)** *if there are **no layout tables** on the page*. ([section508coordinators.github.io](https://section508coordinators.github.io/ACRT/Resources/Trusted%20Tester%20Test%20Process%20v5.1.3.pdf?utm_source=openai))\n\nIn other words: 14.C is only relevant **when you do have layout tables**.\n\n---\n\n## Key Definitions\n\n- **Layout Table**: A table used *solely* to organize or position content (for visual layout), **not** to present data relationships. It does not require header cells because those wouldn\u2019t serve any data context. ([section508.gov](https://www.section508.gov/training/documents/aed-cop-docx05/?utm_source=openai))\n- **Data Table**: A table that presents data in rows/columns, where cells meaningfully rely on row/column headers. Tests for headers, cell associations, etc., apply. ([section508.gov](https://www.section508.gov/training/documents/aed-cop-docx05/?utm_source=openai))\n\n---\n\n## Your Scenario\n\nYou said:\n\n> \u201cI see a data table on a website, but no layout table or any misconfigured table that was intended to be a layout table.\u201d\n\nSo:\n\n- You *see a data table*.\n- You *do not see any layout table* or any misconfigured layout table claiming to be one.\n- The content is *functionally* a data table.\n\n---\n\n## Should You Mark Test 14.C as \u201cDNA\u201d?\n\nGiven the rules:\n\n- **Test 14.C is for layout tables only**. If there are *no layout tables*, then 14.C\u2019s applicability is **does not apply (DNA)**. ([section508coordinators.github.io](https://section508coordinators.github.io/ACRT/Resources/Trusted%20Tester%20Test%20Process%20v5.1.3.pdf?utm_source=openai))\n- If every table on the page is a **data table**, then **14.C does not apply** at all, because there are no layout tables. The test is not relevant.\n- If you had a misused layout table (a layout table using header markup incorrectly, etc.), then 14.C **would apply** and you\u2019d assess whether it meets the requirement (i.e. that it does *not* include headers, or role=\u201dtable\u201d, etc.).\n\nSo in your described situation:\n\n**Yes, you should mark Test 14.C as \u201cDNA\u201d**, because there are *no layout tables present* on the page \u2014 only data tables. Thus 14.C doesn\u2019t apply.\n\n---\n\n## Summary\n\n| Situation | Is there a layout table? | Should Test 14.C apply? | Mark as DNA? |\n|-----------|---------------------------|---------------------------|----------------|\n| Only data tables visible, no layout tables | No | No | **Yes (DNA)** |\n| At least one layout table present | Yes | Yes | **No** (must test it) |\n\n---\n\nIf you want, I can help you double-check whether what you're seeing *might* actually include a layout table (sometimes things look like data tables but are layout tables), so you can be more certain. Do you want me to walk through some cues to distinguish them?"
