+
+Table data is described using an array (rows) of array (cells).

+
+<a name="table-usage-predefined-border-templates-borderless-table"></a>
+#### Borderless Table
+
+Simply using "void" border character template creates a table with a lot of unnecessary spacing.
+
+To create a more plesant to the eye table, reset the padding and remove the joining rows, e.g.
+
+```js
+let output;
+
+output = table(data, {
+ border: getBorderCharacters(`void`),
+ columnDefault: {
+ paddingLeft: 0,
+ paddingRight: 1
+ },
+ drawHorizontalLine: () => {
+ return false
+ }
+});
+
+console.log(output);
+```
+
+```
+0A 0B 0C
+1A 1B 1C
+2A 2B 2C
+```
+
+<a name="table-usage-streaming"></a>
+### Streaming
+
+`table` package exports `createStream` function used to draw a table and append rows.
+
+`createStream` requires `{number} columnDefault.width` and `{number} columnCount` configuration properties.
+
+```js
+import {
+ createStream
+} from 'table';
+
+let config,
+ stream;
+
+config = {
+ columnDefault: {
+ width: 50
+ },
+ columnCount: 1
+};
+
+stream = createStream(config);
+
+setInterval(() => {
+ stream.write([new Date()]);
+}, 500);
+```
+
+
+
+`table` package uses ANSI escape codes to overwrite the output of the last line when a new row is printed.
+
+The underlying implementation is explained in this [Stack Overflow answer](http://stackoverflow.com/a/32938658/368691).
+
+Streaming supports all of the configuration properties and functionality of a static table (such as auto text wrapping, alignment and padding), e.g.
+
+```js
+import {
+ createStream
+} from 'table';
+
+import _ from 'lodash';
+
+let config,
+ stream,
+ i;
+
+config = {
+ columnDefault: {
+ width: 50
+ },
+ columnCount: 3,
+ columns: {
+ 0: {
+ width: 10,
+ alignment: 'right'
+ },
+ 1: {
+ alignment: 'center',
+ },
+ 2: {
+ width: 10
+ }
+ }
+};
+
+stream = createStream(config);
+
+i = 0;
+
+setInterval(() => {
+ let random;
+
+ random = _.sample('abcdefghijklmnopqrstuvwxyz', _.random(1, 30)).join('');
+
+ stream.write([i++, new Date(), random]);
+}, 500);
+```
+
+
+
+<a name="table-usage-text-truncation"></a>
+### Text Truncation
+
+To handle a content that overflows the container width, `table` package implements [text wrapping](#table-usage-text-wrapping). However, sometimes you may want to truncate content that is too long to be displayed in the table.
+
+`{number} config.columns[{number}].truncate` property (default: `Infinity`) truncates the text at the specified length.
+
+```js
+let config,
+ data,
+ output;
+
+data = [
+ ['Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus pulvinar nibh sed mauris convallis dapibus. Nunc venenatis tempus nulla sit amet viverra.']
+];
+
+config = {
+ columns: {
+ 0: {
+ width: 20,
+ truncate: 100
+ }
+ }
+};
+
+output = table(data, config);
+
+console.log(output);
+```
+
+```
+╔══════════════════════╗
+║ Lorem ipsum dolor si ║
+║ t amet, consectetur ║
+║ adipiscing elit. Pha ║
+║ sellus pulvinar nibh ║
+║ sed mauris conva... ║
+╚══════════════════════╝
+```
+
+<a name="table-usage-text-wrapping"></a>
+### Text Wrapping
+
+`table` package implements auto text wrapping, i.e. text that has width greater than the container width will be separated into multiple lines, e.g.
+
+```js
+let config,
+ data,
+ output;
+
+data = [
+ ['Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus pulvinar nibh sed mauris convallis dapibus. Nunc venenatis tempus nulla sit amet viverra.']
+];
+
+config = {
+ columns: {
+ 0: {
+ width: 20
+ }
+ }
+};
+
+output = table(data, config);
+
+console.log(output);
+```
+
+```
+╔══════════════════════╗
+║ Lorem ipsum dolor si ║
+║ t amet, consectetur ║
+║ adipiscing elit. Pha ║
+║ sellus pulvinar nibh ║
+║ sed mauris convallis ║
+║ dapibus. Nunc venena ║
+║ tis tempus nulla sit ║
+║ amet viverra. ║
+╚══════════════════════╝
+```
+
+When `wrapWord` is `true` the text is broken at the nearest space or one of the special characters ("-", "_", "\", "/", ".", ",", ";"), e.g.
+
+```js
+let config,
+ data,
+ output;
+
+data = [
+ ['Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus pulvinar nibh sed mauris convallis dapibus. Nunc venenatis tempus nulla sit amet viverra.']
+];
+
+config = {
+ columns: {
+ 0: {
+ width: 20,
+ wrapWord: true
+ }
+ }
+};
+
+output = table(data, config);
+
+console.log(output);
+```
+
+```
