Emacs: Lines to HTML Table

By Xah Lee. Date: . Last updated: .

Here's a command that turns lines into HTML table.

For example,

a  b  c
1  2  3

becomes

<table class="nrm">
<tr><td>a</td><td>b</td><td>c</td></tr>
<tr><td>1</td><td>2</td><td>3</td></tr>
</table>

and is rendered in browser like this:

abc
123

when you use CSS code similar to this:

table.nrm {border:solid 1px #000000;border-collapse:collapse;margin:.5ex}
table.nrm th, table.nrm td {border:solid thin #808080;padding:.5ex}
table.nrm th {background-color:#d7e4f2}

Solution

(defun xah-html-make-html-table (@separator)
  "Transform the current text block or selection into a HTML table.

If there's a text selection, use the selection as input.
Otherwise, used current text block delimited by empty lines.

*SEPARATOR is a string used as a delimitor for columns.

For example:

a.b.c
1.2.3

with “.” as separator, becomes

<table class=\"nrm\">
<tr><td>a</td><td>b</td><td>c</td></tr>
<tr><td>1</td><td>2</td><td>3</td></tr>
</table>

  (interactive "sEnter the string for column separation:")
  (let ($bds $p1 $p2)
    (setq $bds (xah-get-bounds-of-thing-or-region 'block))
    (setq $p1 (car $bds))
    (setq $p2 (cdr $bds))
    (save-excursion
      (save-restriction
        (narrow-to-region $p1 $p2)
        (let ((case-fold-search nil))

          (goto-char (point-max))
          (insert "\n")

          (goto-char (point-min))
          (while (search-forward @separator nil "NOERROR")
            (replace-match "</td><td>"))

          (goto-char (point-min))
          (while (search-forward "\n" nil "NOERROR")
            (replace-match "</td></tr>\n<tr><td>"))

          (goto-char (point-max))
          (beginning-of-line)
          (delete-char 8)

          (goto-char (point-min))
          (insert "<table class=\"nrm\">\n<tr><td>")

          (goto-char (point-max))
          (insert "</table>")
          ;;
          )))))
