+# Godot Table Container
+
+A Godot plugin that provides a container type that serves as a table.
+I wrote this because the current options for tabular data were insufficient for my use cases.
+
+`GridContainer` was close, but the fact that all the elements must be children of the container created some limitations.
+First, there is no concept of discrete rows, so it was awkward to add sets of nodes as a row to it.
+Second, because of the above, while I was able to instantiate a row scene and then reparent the children to it, the row itself, with any scripting I might have, would be lost.
+
+Combining `VBoxContainer` and `HBoxContainer` is effectively what I do here, but the initial limitation is that the columns do not stay in alignment.
+That's basically what this does.
+
+## Features
+
+* Keeps columns (i.e. `Control` nodes within each `HBoxContainer`) in alignment
+* Has optional auto-update in the game and in the editor
+* Has property to seet horizontal and vertical spacing overrides to the entire table
+
+## Usage
+
+To use, simply create a new `TableContainer` node in your scene tree.
+Add `HBoxContainer` nodes to represent the rows, and ensure that all rows have the same number of columns (children).
+
+The `TableContainer` node has four exported properties:
+
+* `update_interval_editor`, if not `null`, updates the table's alignment in `_process` in the editor every number of frames specified.
+* `update_interval_game`, if not `null`, updates the table's alignment in `_process` in the game every number of frames specified.
+* `separation_horizontal`, if not `null`, applies a value to each row's `HBoxContainer` `theme_override_constants/separation` property.
+* `separation_vertical`, if not `null,` applies a value to the `TableContainer` `theme_override_constants/separation` property.
+
+## Limitations
+
+Anything that's not listed above.
+Rows must be the same length.
+
+## Development
+
+I'm planning to put this to use in another project, and as I see the need, I may extend this.
+It's primarily for my own use, but since I didn't see anything quite like it out there and I've seen it asked about, I figured I'd share!
