How to Edit a Table in Microsoft Word: A Complete Guide

Tables in Microsoft Word are powerful tools for organizing information — but editing them can feel clunky if you don't know where to look. Whether you're resizing columns, merging cells, or changing borders, Word gives you a surprising amount of control once you understand the layout of its table tools.

Where Table Editing Controls Live in Word

When you click anywhere inside a table, Word activates two contextual tabs in the ribbon: Table Design and Layout. These tabs only appear when your cursor is inside a table — they're hidden the rest of the time, which is why many users miss them entirely.

  • Table Design handles visual styling: borders, shading, and preset table styles
  • Layout handles structure: inserting rows and columns, merging cells, adjusting dimensions, and alignment

Getting comfortable with these two tabs covers the vast majority of table editing tasks.

Adding and Deleting Rows and Columns

To add a row, place your cursor in the last cell of the table and press Tab — Word automatically creates a new row below. Alternatively, hover over the left edge of any row and click the + icon that appears, or right-click and choose Insert from the context menu.

To delete a row or column, select it by clicking the row number margin or column edge, right-click, and choose Delete Rows or Delete Columns. Note: pressing the Backspace key deletes the row, while pressing Delete only clears the content inside it — a distinction that trips up a lot of users.

To add a column, right-click any cell in an adjacent column and select Insert → Insert Columns to the Left or Insert Columns to the Right.

Resizing Columns and Rows 🔧

You can resize columns and rows in two main ways:

Manual dragging — Hover over a column border until your cursor changes to a double-headed arrow, then drag left or right. The same applies vertically for row height.

Precise sizing — In the Layout tab, use the Width and Height fields in the "Cell Size" group to enter exact measurements. This is particularly useful for professional documents where consistent sizing matters.

The AutoFit button (also in the Layout tab) gives you three automatic options:

  • AutoFit Contents — shrinks or expands columns to fit the text inside
  • AutoFit Window — stretches the table to fill the full page width
  • Fixed Column Width — locks the current size

Merging and Splitting Cells

Merging cells combines multiple cells into one — common for table headers that span multiple columns.

  1. Select the cells you want to merge
  2. Go to Layout → Merge Cells

Splitting cells does the opposite — divides a single cell into multiple rows or columns.

  1. Click the cell you want to split
  2. Go to Layout → Split Cells
  3. Enter how many columns and rows you want

You can also split an entire table into two separate tables using Layout → Split Table — useful when a long table needs a heading inserted partway through.

Editing Borders and Shading

Under the Table Design tab, you'll find border and shading controls:

OptionWhat It Does
BordersControls which cell edges show a visible border line
ShadingFills selected cells with a background color
Border StylesChanges line type (solid, dashed, dotted)
Pen Color / WeightSets the color and thickness of border lines

For more detailed control, use Borders → Borders and Shading to open a full dialog where you can apply borders to specific sides of selected cells.

Aligning Text Inside Cells

Cell text alignment is separate from paragraph alignment. In the Layout tab, the "Alignment" group offers nine alignment options — combinations of top/middle/bottom vertical alignment with left/center/right horizontal alignment.

This matters most in tables with cells of varying height, where text sitting at the top of a tall cell can look visually disconnected from adjacent content.

Sorting and Formula Options

Word tables support basic sorting — select the table and go to Layout → Sort to alphabetize rows by any column. This works well for simple lists but isn't designed for complex data operations.

Word also supports basic formulas (like =SUM(ABOVE)) inserted through Layout → Formula, though this is limited compared to Excel. If your table involves significant calculations, copying it into Excel and linking it back may produce cleaner results.

Text Direction and Cell Margins ✏️

Two less-obvious but useful edits:

  • Text Direction (Layout tab) rotates text inside cells — handy for narrow header columns
  • Cell Margins (Layout → Cell Margins) controls the internal padding between text and cell borders, which affects readability when cells are tightly packed

Variables That Shape Your Editing Experience

Not all table editing situations are equal. A few factors affect how straightforward or complex your edits will be:

Word version — The interface in Microsoft 365 differs slightly from Word 2016 or Word 2019. Some features (like the hover + for adding rows) appeared in newer versions and aren't available in older ones.

Table origin — Tables pasted from websites or converted from PDFs often have inconsistent formatting, hidden borders, or merged cells that make editing unpredictable. Tables built from scratch in Word are generally easier to modify.

Document complexity — Tables inside text boxes, headers, or multi-column layouts behave differently than standalone tables in the body of a document.

Table style applied — If a built-in table style is active, some manual formatting changes may not appear as expected because the style overrides them. Clearing the style first gives you more direct control.

The right editing approach depends on whether you're making a quick structural adjustment, cleaning up imported content, or building a polished table from scratch — and each of those scenarios calls for a different starting point.
