In this case, it’s the second row that has a width attached to its first table cell. See the Pen Demo for CSS’s table-layout with cell in row 2 given defined width by Louis Lazaris ( on CodePen. Toggling table-layout: fixed adjusts the other columns, but the first one remains the same. In the above demo, the first cell in the table’s first row has a width of 350px. See the Pen Demo for CSS’s table-layout with cell in row 1 given defined width by Louis Lazaris ( on CodePen. The following two demos should help in understanding that the first row of the table is what helps to define the column widths of a table set to table-layout: fixed. How a fixed layout algorithm determines column widths But this time, because one of the columns has extra content, the difference is noticeable. Once again, the same thing is happening the first column is set at 400px then the remaining columns are divided equally. Now if you click the toggle button, you’ll see the columns adjust to accommodate a fixed layout, irrespective of content. See the Pen Demo for CSS’s table-layout property with col width and variable content by Louis Lazaris ( on CodePen. But now let’s add some extra text content to one of the other columns: Since the other three columns have the same content as each other, there will be no change. This happens because the default layout algorithm is essentially saying “make the first column 400px wide, and distribute the remaining columns based on their content”. Notice in this case, toggling table-layout: fixed has no effect. In the following demo, the table has a element whose first element has a width of 400px. If no widths are present on the first row, the column widths are divided equally across the table, regardless of content inside the cells.įurther examples may help make this clearer. When table-layout: fixed is applied, the content no longer dictates the layout, but instead, the browser uses any defined widths from the table’s first row to define column widths. If you click the “Toggle table-layout: fixed” button, you’ll see what the table layout looks like when the “fixed” algorithm is used. As you can see, the browser expands the first column to accommodate the larger bit of content. The demo exaggerates this fact by including a long string of text inside one table cell, while all the other table cells use just two words each.
#Div tabular layout how to
At that point, the table is using the browser’s default algorithm to define how to lay out the table, which means the content will dictate the layout.
When you first view the above demo, you’ll notice the layout of the table columns is unbalanced and awkward. See the Pen Demo for CSS’s table-layout property by Louis Lazaris ( on CodePen. The best way to see the the effects of a fixed table layout algorithm is using a demo. In the demos below, all the table widths are set to 100%, which assumes we want the table to fill its parent container horizontally. In order for a value of fixed to have any effect, the table’s width has to be set to something other than auto (the default for the width property). inherit: indicates that the value is inherited from the table-layout value of its parent.The column values used are based on widths defined on columns or cells for the first row of the table. fixed: With this value, the table’s layout ignores the content and instead uses the table’s width, any specified width of columns, and border and cell spacing values.The resulting table layout is generally dependent on the content of the table. The browser’s automatic algorithm is used to define how a table’s rows, cells, and columns are laid out. But these constraints can be lifted when table-layout is set to fixed. This happens when the table-layout property is set to auto (the default). Browsers will, however, automatically apply certain constraints that will define how tables are laid out. The table-layout property defines what algorithm the browser should use to lay out table rows, cells, and columns.Īs explained in the CSS2.1 specification, table layout in general is usually a matter of taste and will vary depending on design choices.
