Conversation
Result tables were static and, worse, capped at the first 8 rows: the only way to reorder or narrow an answer was to edit the SQL and spend another model call. The rows are already in the browser, so do the work there. Every column header sorts (ascending, descending, back to query order) and carries a filter — substring/exact/prefix on text, a range or a bound on numbers, with the kind inferred from the values so "1,240" and "$18.50" still read as numeric. Above the table sit a cross-column search, a chip per active filter, a clear-all, and CSV copy/download that export the rows the view selects rather than everything. Below it, paging. The view lives on the turn rather than inside the table, so filters survive the flip to the chart and back — and the chart draws the rows the table is showing, not a different set. Also anchors the CSV formula-injection guard, which was unanchored and so prefixed a quote onto any cell merely containing a hyphen — every ISO date in every export. A leading `=`, `+`, `-` or `@` is still escaped. Closes #238 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Svelte 5 bind:value input type number binding value type null
💡 Result:
In Svelte 5, when using bind:value with an input of type="number", the bound variable's value type is typically number | null [1][2][3]. When the input is empty or contains an invalid number, Svelte defaults the bound variable to null [1][2]. This behavior is designed to provide a consistent way to represent the absence of a valid numeric value within the binding system [2]. Key points regarding this behavior: - Type Consistency: While the browser treats all input values as strings, Svelte's bind:value mechanism handles the coercion for type="number" inputs, automatically converting the input to a number when valid, or null when empty/invalid [4][2]. - Null vs. Undefined: Although some documentation or older discussions may have referred to undefined in this context, the internal implementation explicitly uses null for empty or invalid inputs [1][5]. - TypeScript Considerations: Because Svelte's internal binding logic converts these states to null, you should type your bindable variables as number | null to align with the framework's runtime behavior, despite potential mismatches in older type definitions or external linting tools [3][6]. - Form Resets: As of Svelte 5.6.0, if an input has a defaultValue, it will revert to that value upon form reset, provided the current binding value is not null or undefined [7]. If you encounter issues with this type (e.g., in TypeScript), ensure your variable declaration accounts for nullability (e.g., let value: number | null = null;) to avoid type errors [3].

HTML input type=number value sanitization invalid comma currency symbols Svelte bind:value number null official documentation
💡 Result:
For HTML input elements of type="number", the browser's native behavior is to only consider values that represent valid floating-point numbers [1][2][3]. When a user enters characters such as commas (for currency grouping) or currency symbols, these are technically invalid characters for the "number" state [1][3]. The HTML specification dictates that if the value of the input is not a valid floating-point number, the underlying value sanitization algorithm typically treats the input as an empty string ("") [2][4]. Consequently, when you access the.value property of such an input via JavaScript, it may return an empty string if the content is invalid [5]. In Svelte, the bind:value directive simplifies handling numeric inputs by automatically coercing the input value into a number type [6][7]. For an , Svelte's binding behavior is as follows: 1. Valid numeric input: The bound variable is updated with the corresponding number [6][7]. 2. Empty or invalid input: If the input field is empty or contains invalid characters (like currency symbols or commas that the browser does not accept as part of the number), Svelte binds the value as null [6][8][9]. Note that while some early documentation or discussions may have inconsistently used "undefined" or "null" to describe this state [8], the current framework behavior consistently defaults to null for empty or invalid numeric inputs [8][9]. Because browser support for restricting input characters varies [1], developers are encouraged to use type="text" with inputmode="numeric" and a pattern attribute if they require specific character constraints (e.g., to prevent spinbox UI or handle localized currency formatting) [1][3][10].

Use text inputs for numeric filter operands.
columnKind classifies values such as 1,240 and $18.50 as numeric because parseNumeric removes commas and currency symbols. The current type="number" inputs reject these values. Svelte then binds invalid or empty numeric inputs as null, so apply violates the ColumnFilter string contract and isFilterActive treats the filter as blank.

Revoking the blob URL on the same tick can cancel the download.
URL.revokeObjectURL(url) runs immediately after a.click(). Safari and some WebKit builds start the download asynchronously, so the URL can be invalid before the transfer begins, and the file never saves.

Svelte svelte-check --fail-on-warnings default exit code accessibility warnings
💡 Result:
By default, svelte-check does not exit with an error code for accessibility warnings [1]. Svelte-check treats warnings as warnings rather than errors, meaning the command will exit with a 0 status code even if warnings are present [1]. If you want svelte-check to exit with an error code when warnings (including accessibility warnings) are encountered, you must use the --fail-on-warnings flag [2][3][4]. When this flag is enabled, svelte-check will exit with an error code whenever any warning is produced [2][3][4]. Note that there is no built-in way to differentiate the exit code specifically for accessibility warnings versus other types of compiler warnings; if --fail-on-warnings is active, any warning—including accessibility warnings—will trigger the error exit code [5][1]. To selectively handle these warnings, you can either: 1. Use standard svelte-ignore comments in your code to suppress specific accessibility warnings you do not want to trigger a build failure [6][7]. 2. Use the --compiler-warnings option to specify how individual warning codes should be treated (e.g., setting a specific accessibility warning to 'ignore' while leaving others as defaults) [3][4]. For example: --compiler-warnings "a11y-autofocus:ignore" [3].

Make the result cells keyboard-accessible.
td has onclick but no keyboard handler or interactive semantics. Keyboard and screen-reader users cannot activate cell copy, and Svelte emits accessibility warnings. Use a <button> or add role="button", tabindex="0", and Enter/Space handling. CI runs npm run check without --fail-on-warnings, so the warnings alone do not fail CI.

Negative numbers are escaped and lose their numeric type in spreadsheets.
The anchored test is correct for formula injection. It also matches every plain negative number. -5 is exported as '-5, and Excel and Sheets then read that cell as text. A numeric column that contains negative values becomes unusable for arithmetic after export.
Exclude values that parse as a plain number before escaping.

the cell helper in toCSV so formula-injection escaping still applies to values
beginning with =, +, -, or @, but skips plain numeric values that parse as
numbers, including negative numbers. Preserve CSV quoting behavior and the
existing row separator.

User description
Result tables were static and, worse, capped at the first 8 rows: the only way to reorder or narrow an answer was to edit the SQL and spend another model call. The rows are already in the browser, so do the work there.
Every column header sorts (ascending, descending, back to query order) and carries a filter — substring/exact/prefix on text, a range or a bound on numbers, with the kind inferred from the values so "1,240" and "$18.50" still read as numeric. Above the table sit a cross-column search, a chip per active filter, a clear-all, and CSV copy/download that export the rows the view selects rather than everything. Below it, paging.
The view lives on the turn rather than inside the table, so filters survive the flip to the chart and back — and the chart draws the rows the table is showing, not a different set.
Also anchors the CSV formula-injection guard, which was unanchored and so prefixed a quote onto any cell merely containing a hyphen — every ISO date in every export. A leading
=,+,-or@is still escaped.Closes #238
