The grid every other Tables page builds on. A table holds your rows and the columns that describe them. This page covers the grid itself, which every other page in Tables assumes you already know. A table grid holding fifty rows of people. The header shows the first of ten columns, First Name, Last Name, Full Name, Email, Email Status and Deliverable, each with a type icon and a fill bar reading 100 percent. Above the grid a toolbar holds Auto-run, a queue count, the view switcher, a 10/10 columns control, filter, sort and search. The footer reads 50 rows. ## Work with rows and cells Click **Tables** in the sidebar, then click a table to open its grid. Click a cell to select it, then type to replace what is there. Double-click to edit the existing value instead. At the bottom of the grid, set a count and click **Add**. The rows land empty at the end. Hover a row's gutter and click the expand icon. The panel lists every visible column as a labelled field, which is easier than scrolling sideways. Columns are their own subject. Start at [Add a column](/tables/columns/add-a-column), which covers every kind and how to tell which one you need. ## Act on several rows at once Tick a row's checkbox in the gutter, or the header checkbox for the whole page, then click **Actions**. The **Actions** menu can run every enrichment column over the rows you ticked, which spends credits. The cost shows before you confirm. ## Good to know A delete shows an undo for a few seconds. After that the rows are gone for good. Clearing empties the value and leaves the row in place. A computed column will fill it again on its next run. Values that cannot be read as the new type are cleared, so switching a text column to **Number** loses anything that was not a number. A table always shows at least one column, so the last one cannot be hidden or deleted. Double-click a header to rename it in place, or open its menu for **Rename column**. Drag a header to reorder it. The columns control in the toolbar shows a count, like "10/10 columns". Open it to hide a column or drag it to a new position. A selected cell has a drag handle at its corner that fills its value down the column. Pasting more rows than the table holds adds the extra rows. A cell holding a whole record shows as a single value in the grid. Open the row panel and it unpacks into its fields, each of which you can give its own column. ## Next steps Add a column that fills itself in from outside data. Compute a column from the data you already have, for free. Change what you are looking at without touching the data. Decide when a computed column fills its cells.
