Summary

CMS content pages with tables grew borders after #333. That PR styled each th and td inside .content-block with a border, cell padding and a header fill so that a table inserted from the new editor table dialog would be visible. Migrated VIPER 1 content uses borderless layout tables (CAHFS Home alone has seven), so those pages picked up borders they never had. VIPER 1 rendered the same HTML with no table CSS at all.

Regression from #333.

Fix

The bordered styling now keys off a border attribute on the table instead of applying to every table in the block.

  • base.css scopes those rules to table[border], with border="0" left alone. A table without the attribute renders with browser defaults, the way it did in VIPER 1.
  • The editor's table dialog gains "Show borders" (on by default) and "Alignment" (not set, left, center, right), in the order CKEditor's dialog listed them. It writes border="1" or border="0" plus the align attribute when one is chosen. A survey of the stored blocks found 6 of 15 with tables chose border 0 in CKEditor and 7 carry align, so both are in use; none use caption or summary, so those are not offered.
  • The sanitizer lets border, align, valign, cellpadding and cellspacing through. VIPER 1's AntiSamy policy allowed all five, so legacy content that carries them renders as it used to. One block (IACUC Protocols) had border="1" stripped before VPR-210 feat(cms): add link, image and table dialogs to the content editor #333 and gets its borders back.
  • In the editor, a table with borders off shows a 1px dotted cell guide so it stays findable while editing, the way CKEditor's showborders plugin did in VIPER 1. The rule is scoped to the editor, so the page still renders it borderless.
  • q-table and CMS tables each carried their own #eee header fill. It now lives in a --table-header token in colors.css, with a line in DESIGN.md.

Testing

  • editor-html and rich-text-editor suites cover the attributes, including a borderless centered insert driven through the dialog.
  • Sanitizer tests check that border="1", align, valign, cellpadding and cellspacing survive a sanitize pass.
  • Checked CAHFS Home in the browser: legacy cells have no border and no header fill, an injected border="1" table gets the styling, and border="0" does not.
  • In the editor, a borders-off insert computes to a 1px dotted cell border and a bordered insert to 1px solid; CAHFS Home cells still compute to no border.
  • Opened the dialog on the content block editor: fields appear as Rows, Columns, First row is a header, Show borders, Alignment, and inserting with borders off and Center selected writes <table border="0" align="center">.

📝 Walkthrough

Walkthrough

The table editor now supports border and alignment options. Generated table HTML includes these attributes, CSS applies bordered-table styles conditionally, and sanitization preserves the attributes.

Changes

Table options

Layer / File(s) Summary
Table options contract and editor flow
VueApp/src/components/editor/editor-html.ts, VueApp/src/components/editor/EditorTableDialog.vue, VueApp/src/components/RichTextEditor.vue, VueApp/src/components/__tests__/*
TableOptions and TableAlign define the shared table shape. The dialog collects border and alignment values, emits the shared payload, resets all fields, and generates matching table HTML.
Table styling and shared header color
VueApp/src/styles/colors.css, VueApp/src/styles/base.css, DESIGN.md
A shared --table-header token replaces hard-coded header colors. CMS table borders, padding, and header fills apply only when border is not "0".
HTML attribute preservation
web/Services/HtmlSanitizerService.cs, test/Services/HtmlSanitizerServiceTests.cs
The sanitizer allowlist now preserves border, align, valign, cellpadding, and cellspacing attributes. Tests cover these attributes.

🟢 Approval recommended

The changes are tightly scoped to the regression, align with legacy content behavior, and are backed by targeted frontend + sanitizer tests.

Pull request overview

Fixes a regression introduced in #333 where all CMS tables inside .content-block became bordered, by making the “bordered table” treatment opt-in via the legacy border attribute (matching VIPER 1 behavior for migrated layout tables).

Changes:

  • Scope CMS table borders/padding/header-fill styling to table[border] (excluding border="0"), and centralize the header fill color in a shared --table-header token.
  • Extend the rich text editor’s table dialog to capture “Show borders” and “Alignment”, emitting border="1"/"0" and optional align.
  • Update HTML sanitization allowlist and add/adjust tests to preserve legacy table presentation attributes and verify dialog output/reset.
File summaries
File Description
web/Services/HtmlSanitizerService.cs Allows legacy presentational table attributes (border/align/valign/cellpadding/cellspacing) to survive sanitization.
test/Services/HtmlSanitizerServiceTests.cs Adds test coverage ensuring the newly-allowed table attributes are preserved.
VueApp/src/styles/colors.css Introduces --table-header token to avoid duplicated header-fill literals.
VueApp/src/styles/base.css Uses --table-header for q-table headers and scopes CMS table styling to table[border]:not([border="0"]).
VueApp/src/components/RichTextEditor.vue Updates table submit typing to use the shared TableOptions shape.
VueApp/src/components/editor/EditorTableDialog.vue Adds “Show borders” and “Alignment” controls; switches to a single reactive form object with full reset.
VueApp/src/components/editor/editor-html.ts Extends buildTableHtml to emit border="1"/"0" and optional align, and exports TableOptions/TableAlign.
VueApp/src/components/tests/rich-text-editor.test.ts Updates table insertion expectation and adds a dialog-reset regression test.
VueApp/src/components/tests/editor-html.test.ts Updates expected table HTML and adds coverage for border="0" + align.
DESIGN.md Documents that table-header applies to both q-table headers and bordered CMS content tables.

The code itself looks good, but I'm not sure how usable a new borderless table will be in the WYSIWYG editor - it's very hard to find the cells and might look like it wasn't inserted at all. I'm not sure what the solution is, though, since this is WYSIWYG.

The editor parity work styled every table cell inside rendered CMS
content with a border, cell padding and a header fill so that a table
inserted from the new table dialog would be visible. Migrated VIPER 1
content uses borderless layout tables, so pages like CAHFS Home grew
borders they never had.

- Key the bordered styling off a border attribute on the table, which
  the sanitizer now lets through as the VIPER 1 policy did; border="0"
  stays borderless
- Give the table dialog "Show borders" and "Alignment" options in
  CKEditor's order, writing the border and align attributes VIPER 1
  content already uses
- Let align, valign, cellpadding and cellspacing through the sanitizer
  as well, the presentational table attributes VIPER 1's policy allowed
- Tables without the attribute render with browser defaults again, and
  the editor alone draws a dotted cell guide on them so a borderless
  table stays findable while editing, as CKEditor's showborders did
- Share the table header fill between q-table and bordered CMS tables
  through a --table-header token

@bniedzie Similar to the html editor on VIPER1, there is a faint dotted line on tables with border = 0 that only shows up in the editor.
