Table cell prettification
The following script pads the table cells with spaces so that all are of equal width. The bookmarkable link is here
The source code:
- source.js
(function() { var editor = window.document.getElementById('wiki__text'); var lines = editor.value.split('\n'); var next = function(l, n) { var a = lines[l].substr(n).indexOf('^'); var b = lines[l].substr(n).indexOf('|'); if(a === -1 && b === -1) { return -1; } var r; if(b === -1) { r = a + n; } else if(a === -1) { r = b + n; } else { r = (b < a ? b : a) + n; } if(r > 0 && lines[l].charAt(r - 1) === '|' || lines[l].charAt(r - 1) === '^') { while(lines[l].charAt(n) !== '|' && lines[l].charAt(n) !== '^') { n++; } return next(l, n+1); } else { return r; } }; var insert = function(c, l, n, p) { var s = ''; for(var i=0;i<n;i++) { s+=c; } lines[l] = lines[l].substr(0, p) + s + lines[l].substr(p); }; var tl, cols = null, c = -1, x = -1, dx, px = -1; for(var l = 0; l < lines.length;) { x = next(l, x + 1); if(x === -1) { l++; c = -1; if(px === -1 || l === lines.length) { if(cols !== null) { for(var i = tl; i < l-1;i++) { x = next(i, 0); px = x; for(var j = 0; j < cols.length;j++) { x = next(i, x + 1); if(px !== -1) { if(x === -1) { insert(' ', i, cols[j], px + 1); x = px + 1 + cols[j]; insert(lines[j].charAt(px), i, 1, x); } else { insert(' ', i, cols[j] - x + px + 1, x); x += cols[j] - x + px + 1; } } px = x; } } } px = -1; x = -1; cols = null; } else { px = -1; } } else if(px !== -1) { if(cols === null) { cols = []; tl = l; } c++; dx = x - px - 1; if(typeof cols[c] === 'undefined' || cols[c] < dx) { cols[c] = dx; } } px = x; } editor.value = lines.join('\n'); })();
