Column is a layout element within Blocks that renders all children vertically. The widths of columns can be set through the `scale` and `min_width` parameters. |
|
If a certain scale results in a column narrower than min_width, the min_width parameter will win. |
|
Example: |
|
with gr.Blocks() as demo: |
|
with gr.Row(): |
|
with gr.Column(scale=1): |
|
text1 = gr.Textbox() |
|
text2 = gr.Textbox() |
|
with gr.Column(scale=4): |
|
btn1 = gr.Button("Button 1") |
|
btn2 = gr.Button("Button 2") |

Parameters: |
|
scale: relative width compared to adjacent Columns. For example, if Column A has scale=2, and Column B has scale=1, A will be twice as wide as B. |
|
min_width: minimum pixel width of Column, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in a column narrower than min_width, the min_width parameter will be respected first. |
|
variant: column type, 'default' (no background), 'panel' (gray background color and rounded corners), or 'compact' (rounded corners and no internal gap). |
|
visible: If False, column will be hidden. |
|
elem_id: An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles. |
|
elem_classes: An optional string or list of strings that are assigned as the class of this component in the HTML DOM. Can be used for targeting CSS styles. |
|
render: If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later. |
|
show_progress: If True, shows progress animation when being updated. |
