docs(table): document per-column width controls (fixed px / flexible weight, bulk, fit-to-content) (cube-js#11180)

Documents the per-column width model for table charts: Fixed (px) / Flexible (weight) modes, drag-to-resize, per-column and bulk fit-to-content, and All flexible / All fixed / All fit to content bulk controls with their enablement rules.

+## Column width
+
+Each column's width is set independently in the **Columns** section of the **Style** tab. A column is in one of two modes:
+
+- **Flexible** (the default) — the column shares the table's available width with the other flexible columns, in proportion to its **weight**. A column with weight `2` is twice as wide as a column with weight `1`. New columns start at weight `1`, so by default all columns share the width equally and the table stretches to fill its tile.
+- **Fixed** — the column is locked to an exact pixel width and no longer participates in the weight-based distribution. Fixed columns keep their width regardless of the tile size; if the fixed columns don't fill the tile, the remaining space is left blank.
+
+You can mix the two: give a label column a fixed width and let the metric columns flex to share the rest.
+
+### Setting widths
+
+- **In the panel** — pick **Flexible** or **Fixed** for a column and enter its weight or pixel value.
+- **By dragging** — drag the border between two column headers on the table. The change is saved into the column's current mode (a flexible column keeps flexing at its new relative size; a fixed column updates its pixel width).
+- **Fit to content** — the **Fit to content** button next to a column's width sizes it to its content and switches it to **Fixed** at that width.
+
+  <Note>
+
+  Fit to content measures the rows currently rendered on screen. If a wider value is further down a long, scrolled table, fit to content again after scrolling to it.
+
+  </Note>
+
+### Bulk controls
+
+At the top of the **Columns** section:
+
+- **All flexible** — converts every column to flexible, deriving each weight from its current width (so the layout doesn't jump). Enabled only when at least one column is fixed.
+- **All fixed** — freezes every column at its current rendered pixel width. Enabled only when at least one column is flexible.
+- **All fit to content** — sizes every column to its content and fixes it at that width, in a single action (the bulk equivalent of the per-column **Fit to content**). Like per-column fit to content, it measures the rows currently rendered on screen.
+
+<Note>
+
+Under a column pivot, a width set on a measure applies to every column generated for that measure.

 By default, columns display their raw value. The **Display** tab for each field lets you change this:
