# CHANGES IN lt VERSION 0.4

- `lt_format()` gained a `sig_digits` argument to format numbers to a fixed number of significant digits (e.g., `lt_format(x, ~col, sig_digits = 3)`), which is useful for columns spanning several orders of magnitude. It is mutually exclusive with `decimals`.

- Missing (`NA`) cells now display an em dash (`—`) by default instead of an empty cell, so they are no longer confused with empty strings. Change the table-wide default with the `lt.missing` global option, e.g., `options(lt.missing = "n/a")`, or set it to `""` to keep `NA` cells blank. `lt_sub(missing =)` still overrides the text for specific columns.

# CHANGES IN lt VERSION 0.3

- `lt_width()` can set the width of the whole table via an unnamed argument, e.g., `lt_width("80%")`. It can be combined with named column widths.

- Column selection now accepts integer positions in addition to column names and one-sided formulas, e.g., `lt_align(x, 1:2, "center")` or `lt_spanner(x, "Grp", columns = 2:3)`. This applies to all functions that select columns (`lt_align()`, `lt_spanner()`, `lt_format()`, `lt_date()`, `lt_footnote()`, `lt_html()`, `lt_sub()`, `lt_merge()`, `lt_style()`, `lt_move()`, and `lt_group()`).

# CHANGES IN lt VERSION 0.2

- Added support for raw HTML in tables. Cell values and text are HTML-escaped by default; to emit raw HTML instead, mark whole body columns with `lt_html()`, or wrap the text passed to `lt_header()`, `lt_label()`, `lt_spanner()`, `lt_footnote()`, or `lt_note()` in `I()`.

- Added `lt_export()` to save an lt table to a file: `.html` (an HTML table, optionally baked to a static `<table>` via Node.js or a headless browser so it needs no JavaScript to view), `.pdf` (a vector PDF), or `.png` (a raster image). PDF and PNG are rendered in a headless Chromium browser and cropped tightly to the table by default.

# CHANGES IN lt VERSION 0.1

- Initial CRAN release.
