# Tables

With tables, you can organize ordered pairs, quickly plot points for a particular function, or even run regression to find a line or curve of best fit. And the circle icon at the top allows you to tweak more than just the color: adjust the style (dots, connected, or both) or convert the entire table into movable points with just a click! Get started with the video on the right, then dive deeper with the resources and challenges below.

## Getting Started with Tables

Entering tables is easy depending on what type of data you're looking to enter. To add a blank table, open the Add Item menu and choose Table. You can also type 'table' in a blank expression line.

Enter values into the table and use the arrow keys to easily maneuver through the table. Click on the zoom fit icon to automatically adjust the axis settings to fit the data.

## Scatter Plots

You can also copy and paste data from an existing spreadsheet. Desmos will automatically generate a table.

Note: The column header titles will not transfer and there is a maximum of 1000 rows that are able to be copy and pasted in a table. Copying and pasting more than 1000 rows will generate more than one table.

## Function Tables

Columns of tables at Desmos.com have different behavior depending on their headings. If you put a function of x in the 2nd header we'll fill it in as a function table, calculating the values for you. For example, if you have "$$x_1$$" and "$$sin (x_1)$$" as your headings, we'll fill in the 2nd column for any point you put in the first.

You can write rich math expressions in the cells, including things like $$\frac{\pi}{2}$$.

You can compare two functions side by side, add another column and enter another function into the new heading.

You can define a function in an expression line and use it in your table to evaluate based on your $$x$$ values.

## Convert a Function to a Table

Expressions and points can be shown as tables using Convert to Table. To start, click the Edit List button. If the expression line contains an available expression, a Convert to Table button will appear. Click on it to transform the expression line to a table.

Equations, expressions, points, and lists of points can be converted to a table.
