styling

CSS and Tailwind rules for styling a reusable data-table library without interfering with the application's other styles.

In plain words
What is it for?
Use them when editing the table's CSS, Tailwind configuration, component classes, or loading styles for skeleton states.
Why use it?
They prevent style conflicts, unwanted global rules, and unnecessary third-party CSS in the library bundle.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 573 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

styling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Styling Rules

CSS Architecture

The library has two styling layers:

  1. src/styles/tableStyles.css — Scoped component CSS, wrapped in @layer rtbl { ... } to prevent cascade conflicts with consumer styles. All selectors use the rtbl- prefix.
  2. Tailwind utility classes — Applied inline in JSX for dynamic, state-driven styles (dark mode, hover, responsive).

@layer rtbl Requirement

All rules in tableStyles.css MUST live inside @layer rtbl { ... }. Never add bare/global rules.

Reason: CSS Cascade Layers (@layer) ensure library styles have lower specificity than any unlayered consumer styles, so the library never wins a specificity war.

rtbl- Prefix

Every class defined in tableStyles.css MUST start with rtbl-. This prevents naming collisions with consumer CSS frameworks or component libraries.

Never @import Third-Party CSS Here

@import "react-loading-skeleton/dist/skeleton.css" was intentionally removed. The skeleton CSS is loaded by TableSkeleton.tsx via a JS import, which only runs when the component is actually rendered. Do NOT re-add any @import of third-party CSS to tableStyles.css — it would bundle those styles into dist/index.css unconditionally.

Tailwind Config (tailwind.config.js)

  • preflight: false — disables Tailwind's CSS reset to avoid affecting consumer pages
  • Content paths scan only ./src/**/*.{js,ts,jsx,tsx} — do not widen this

Dark Mode in Tailwind

The library uses class-based dark mode via isDarkMode state + .dark class on the container. CSS dark variants target .rtbl-container.dark .rtbl-*. Tailwind dark utilities (dark:bg-gray-700) work because enableDarkMode adds .dark to the container class.

Consumer Setup (Tailwind v3)

Consumers must add the library to their content array for Tailwind to scan its classes:

// tailwind.config.js
module.exports = {
  content: [
    "./src/**/*.{js,ts,jsx,tsx}",
    "./node_modules/nextjs-reusable-table/dist/**/*.{js,mjs}",
  ],
};

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

styling is a cursor rule published in the GitHub repository ninsau/nextjs-reusable-table (6 stars, last pushed 5mo ago), licensed 0BSD. It costs nothing until one of its globs matches a file; then it loads 573 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
